Mizoram Corridor Exposed: How 7 Foreign Operatives Slipped Through India’s Borders to Train Insurgents

— And Why It Took NIA Far Too Long to Notice?

Part One: The Last Flights Out

On the morning of Friday, March 13, 2026, three separate teams from India’s National Investigation Agency (NIA) moved simultaneously through three different airports — Kolkata, Delhi, and Lucknow. Their targets were not hardened terrorists slipping through shadows. They were men carrying passports from Ukraine and the United States, men who had stood on the battlefields of Libya, Syria, and the killing fields of the Russia-Ukraine war.

One of them— Matthew Aaron VanDyke, an American from Baltimore— was picked up at Netaji Subhas Chandra Bose International Airport in Kolkata. He had a documentary filmmaker’s biography and a mercenary’s curriculum vitae. Three Ukrainian nationals were pulled from departing queues at Indira Gandhi International Airport in Delhi. Three more were intercepted at Chaudhary Charan Singh International Airport in Lucknow.

Seven men. Three cities. One operation.

That coordination tells you something important: the NIA had been watching these men for a while. What it also tells you — and what should trouble every thoughtful Indian — is that the agency nearly missed them entirely. The men were leaving. Their work, apparently, was done.

Part Two: Who Were These People?

Begin with VanDyke, because he is the most visible and, therefore, the most instructive.

His website describes him as a soldier, a war correspondent, a businessman, and the founder of an organisation called Sons of Liberty International, or SOLI— a private military contracting firm that, in his telling, trains fighters for just causes against authoritarian regimes. He has fought alongside rebel forces in the Libyan Civil War against Muammar Gaddafi, was captured and held as a prisoner of war for nearly six months in 2011, and later made a documentary about the experience. He has been documented on the frontlines in Syria. He trained Ukrainian civilians to fight Russian forces after the 2022 invasion. By the time of his arrest, he was a man whose biography read like a Pentagon-approved adventure serial.

The six Ukrainians arrested alongside him — Hurba Petro, Slyviak Taras, Ivan Sukmanovskyi, Stefankiv Marian, Honcharuk Maksim, and Kaminskyi Viktor— are more shadowy figures publicly, though NIA filings describe them as war veterans with combat experience. Three of them, at minimum, are reported to have served in active conflict zones.

These are not amateurs. They are men who know how to cross borders, how to move equipment, how to train fighters, and how to disappear into the bureaucratic noise of a country where tourism paperwork is inconsistently enforced.

They knew exactly what they were doing. The question India needs to answer is: who pointed them here, and why?

Part Three: The Paper Trail— Tourist Visas and a Deliberate Deception

According to the NIA’s First Information Report, the seven men entered India on ordinary tourist visas. This is, on its surface, unremarkable. India issues millions of tourist visas every year. What follows is less unremarkable.

From their points of entry, they made their way to Guwahati, the largest city in Assam and the de facto gateway to India’s Northeast. From Guwahati, they travelled south-west into Mizoram — a state that requires a separate Restricted Area Permit (RAP) for most foreign nationals. They did not obtain this permit.

Then, from Mizoram, they crossed into Myanmar’s Chin State — a region dominated by Chin ethnic armed organizations that have been in revolt against the Myanmar military junta since the 2021 coup. In Chin State, according to NIA filings, they conducted pre-scheduled training for Ethnic Armed Groups that maintain documented operational links to insurgent organizations proscribed in India: ULFA-Independent, the NSCN, and the Kuki National Army.

The training was specific and sophisticated: drone operations, drone assembly, electronic jamming technology, and weapons handling. A large consignment of drones — sourced from Europe — was also reportedly channeled through this corridor into Myanmar.

Then, completing the loop, they re-entered India through the same unfenced border. They were heading for their departure airports when the NIA closed in.

The route they used — Guwahati to Mizoram to Myanmar’s Chin Hills and back — is not an accidental discovery. It is a known corridor. And knowing it was known makes the question of how they evaded detection for so long all the more pointed.

Part Four: The Open Secret Nobody Acted On

Here is something that has been sitting in the public record, mostly unread: in March 2025, a full year before these arrests, Mizoram’s own Chief Minister Lalduhoma stood in the state assembly and warned that his state was being used as a “secret transit route” by foreigners heading into Myanmar. He told legislators that between June and December 2024 alone, nearly 2,000 foreign nationals had entered Mizoram — many of whom appeared to bypass tourism entirely and crossed into Myanmar’s Chin Hills for what he described as military training purposes.

The Chief Minister also said something that deserves to be read slowly: “In the present geopolitics, the situation in Myanmar is being closely viewed by global powers including China and the US.”

He said it openly. In a state assembly. In 2025.

The NIA made its arrests in March 2026.

That is a twelve-month gap between a sitting Chief Minister naming the problem and federal enforcement catching the people responsible for it. The question of what happened in those twelve months— what intelligence was shared, what was ignored, what local police were told, what the central government was briefed— is one that deserves a parliamentary answer.

Part Five: The Border That Barely Exists

To understand how seven foreign military veterans moved through Northeast India with drone equipment without detection, you have to understand the India-Myanmar border.

It runs for 1,643 kilometres across four states: Arunachal Pradesh, Nagaland, Manipur, and Mizoram. It passes through some of the most physically difficult terrain in Asia — dense jungle, steep ridges, river valleys that flood seasonally, and forest cover so thick that satellite surveillance struggles to penetrate it.

The entire border is managed by the Assam Rifles, one of the oldest paramilitary forces in India. Of its roughly 46 battalions, approximately 20 are actually deployed for border guarding. The rest handle counter-insurgency operations in the hinterland. The border is not fenced — indeed, as of early 2025, barely 10 per cent of the planned fencing had been completed, and Mizoram’s Chief Minister himself had opposed the fencing project on the grounds that it would sever the cultural and familial ties between Mizo and Chin communities on either side.

Under the now-suspended Free Movement Regime, people living within 16 kilometres of the border on either side could cross without a visa — facilitating genuine trade and cultural contact, but also creating a permissive environment for anyone who knew the terrain. The regime was officially suspended in 2023, but enforcement of the new rules has been, by all accounts, inconsistent.

In Mizoram, the Assam Rifles operates from Company Operating Bases, not from continuous border outposts. This creates gaps — physical gaps in surveillance, not just administrative ones. The jungle does the rest.

For trained soldiers who have operated in Libya and Syria, crossing such a border would be, professionally speaking, not particularly challenging.

Part Six: The Logistics of Invisibility

How do you move drones from Europe into Myanmar through India without anyone noticing?

The NIA’s own FIR gives us part of the answer by describing the scale of what was moved as a “huge consignment.” But the method is worth examining, because it points to an operational sophistication that goes beyond a group of freelancers improvising on the fly.

Modern FPV (First Person View) drones — the kind used with devastating effect in the Ukraine conflict — are small enough to be disassembled and transported as consumer electronics. A drone in pieces looks like a camera kit, or a hobbyist’s equipment bag. Batteries can be carried separately, declared as power banks. Controllers and jammers can pass through customs as radio equipment. None of it is individually suspicious. Together, in a consignment, it becomes a weapons system.

The group reportedly flew into Guwahati, then moved into Mizoram by road. Local police in Mizoram were, apparently, not alerted. The Restricted Area Permit requirement — the one mandatory checkpoint that should have flagged these men — was either not enforced or not checked. The men crossed into Myanmar. They did their training. They came back. They split up across three cities to make their departures less conspicuous.

It worked. Until it didn’t.

The NIA has not publicly disclosed what intelligence triggered its eventual pursuit of these men. The most credible hypothesis— advanced by several analysts and notably by Russian-American commentator Andrew Korybko— is that India was tipped off by Russian intelligence, which maintains close surveillance of Ukrainian mercenary networks globally. This would be consistent with India’s carefully maintained relationship with Moscow even as it navigates ties with Washington. If true, it would mean that a foreign intelligence service caught what India’s own border management failed to prevent.

Part Seven: Deep State Questions— Who Invited Them?

This is where honest journalism must be careful about the line between documented fact and reasonable probability. The NIA has charged the seven men under the Unlawful Activities Prevention Act, including Section 18 covering terrorist conspiracy. The investigation is ongoing. Eight more Ukrainian nationals linked to the case remain at large.

But the deeper question is not whether these men did what they are accused of. It is who facilitated their entry into this very specific operational theatre.

VanDyke is the founder of Sons of Liberty International, an organisation that has publicly positioned itself as training fighters against authoritarian regimes — in Libya, Syria, Iraq, Ukraine. Myanmar‘s military junta is, by most measures, an authoritarian regime. Training the Chin resistance fighters who oppose it is ideologically consistent with SOLI‘s stated mission.

But the Chin resistance’s links to Indian-proscribed insurgent groups — ULFA-I, the NSCN— complicate that framing significantly. Those groups are not fighting authoritarian regimes in a foreign country. They are organisations with histories of violence against the Indian state and its citizens. Providing drone and jamming training to armed groups with documented ties to them is not freedom fighting. Under Indian law, it is terrorism.

So who commissioned this specific operation? Who told VanDyke that Mizoram was the entry point, that the Chin State was the destination, that these particular Ethnic Armed Groups needed this particular training?

The possibilities are worth laying out plainly, because honest analysis requires naming them even when it is uncomfortable.

Ukraine. Kyiv has been aggressively building intelligence and special operations capacity since the Russian invasion. President Zelensky declared in early 2025 that Ukraine needed a foreign operations unit capable of “real combat and other asymmetric operations” abroad. Ukrainian mercenary networks have been documented in Sudan and Mali. Whether this operation in India was sanctioned at the state level, conducted by a rogue network for profit, or deliberately structured to give Kyiv plausible deniability is unknown. Ukraine’s ambassador to India has demanded the immediate release of its nationals and claimed there are “no established facts” of illegal activity — a diplomatic posture, not a denial.

Elements within US policy networks. VanDyke’s Sons of Liberty International has received media coverage suggesting links to US government-adjacent funding streams. The organisation has a history of operations that align with American foreign policy objectives in the Middle East. Whether Washington sanctioned, encouraged, or was genuinely ignorant of this specific India operation cannot be determined from available evidence. The US Embassy’s response — “we are aware of the situation, but cannot comment for privacy reasons” — is the most non-committal possible statement.

Private sponsors with geopolitical interests. The Myanmar civil war has drawn in an array of private and state actors with financial and strategic interests. Arms dealers, diasporas funding resistance movements, governments with interests in keeping the Myanmar junta destabilised — any of these could have funded a training operation through channels that give states plausible deniability.

Domestic facilitators. How did a group of foreign nationals know to fly into Guwahati? How did they know the Mizoram route? How did they arrange “pre-scheduled” training with specific armed groups? Someone on the ground — or connected to the ground — provided the local knowledge. The NIA investigation’s most important thread may not be the seven men already in custody, but whoever is still free and still in India.

Part Eight: The Strategic Stakes — Why the Northeast, and Why Drones?

Drones are the defining weapon technology of the 2020s. The Ukraine conflict demonstrated what even moderately skilled operators with consumer-grade FPV drones can do to armoured columns, supply lines, and fixed installations. The lesson was not lost on insurgent groups globally.

In India’s Northeast, the security establishment learned this lesson unpleasantly in July 2025, when ULFA-Independent used drone strikes — reportedly involving over 100 UAVs — against Indian Army camps in Myanmar’s Sagaing Region. Regardless of who ultimately launched those drones (the Indian Army denied involvement; ULFA-I pointed at India), the event demonstrated that drone warfare has arrived in this theatre.

Against that backdrop, a group of foreign veterans providing drone assembly, operations, and jamming training to Ethnic Armed Groups with ties to ULFA-I and the NSCN is not an abstract security concern. It is the direct transfer of proven combat technology to organizations that have demonstrated the will to use it.

The Chin State, where this training reportedly occurred, sits directly on India’s border. A drone operator trained there, with European-sourced equipment, operating from the dense forest cover of Myanmar’s hills, could threaten Indian military installations, border outposts, and infrastructure in Manipur, Mizoram, or Nagaland within operational range.

Now consider the Siliguri Corridor — the so-called “Chicken’s Neck” — the narrow strip of Indian territory that connects the seven northeastern states to the rest of India. It is, at its narrowest, less than 22 kilometers wide. Military strategists have long identified it as India’s most acute geographical vulnerability. Bangladesh’s political instability and China’s expanding influence have already sharpened official anxiety about its security. An insurgent force equipped with sophisticated drones and jamming technology, operating from multiple directions, could — in a worst-case scenario — threaten both the corridor’s infrastructure and India’s ability to respond.

This is not hypothetical catastrophizing. It is the logical extension of what the NIA says these seven men were building.

Part Nine: How the NIA Finally Moved

India’s National Investigation Agency is the country’s federal counter-terrorism body, established after the 2008 Mumbai attacks. It operates across state lines, beyond the jurisdictional limitations of state police, and with the authority to take up cases under the UAPA directly.

The NIA registered its case on March 13, 2026 — the same day as the arrests — following directions from the Ministry of Home Affairs. The coordinated, simultaneous detention of seven people across three airports in three different cities suggests the NIA had built substantial intelligence before acting. You do not orchestrate that kind of precision without preparation.

The most significant question — what triggered the NIA’s investigation, and when — has not been officially answered. Intelligence sharing between India and Russia remains a realistic explanation given Moscow’s documented interest in tracking Ukrainian mercenary networks. Digital forensics may also have played a role: the group’s mobile phones, now seized, reportedly contain evidence that investigators expect will map the full funding and logistics chain.

The NIA sought 15 days of custody from a special court in Delhi. The court granted 11. The seven remain in custody through March 27, 2026, and the investigation is explicitly described as part of a “wider international conspiracy.” Eight more Ukrainian nationals linked to the operation remain unaccounted for.

Part Ten: The Accountability Gap

There is a tendency in Indian security commentary to frame arrests like these as vindication — proof that the system works, that the agencies are vigilant, that India is protected. That reading is too comfortable.

The more honest reading is this: seven foreign military veterans moved through India’s Northeast with drone equipment, conducted covert training sessions with insurgent-linked armed groups, transported a large consignment of European-sourced drones through Indian territory into a neighbouring country, and then re-entered India — all without the Mizoram state police, the Assam Rifles, the Bureau of Immigration, or local intelligence flagging anything in real time.

They were caught because they were leaving. Not because they were caught operating.

The warning signs were in the public record. Mizoram’s Chief Minister had named the problem twelve months before these arrests. Nearly 2,000 foreign nationals had entered his state in a single six-month period, many of them heading into Myanmar’s Chin Hills for what he described as military training. The intelligence existed. The political will to act on it — or the mechanisms to translate that political statement into an operational response — apparently did not.

This gap between awareness and action is the real story. It is more troubling than the mercenaries themselves, because it describes a systemic vulnerability rather than a one-off event. If this group could do it, others have done it before and others will attempt it again — especially now that drone warfare has proven its value in this theatre and the Myanmar civil war shows no sign of resolution.

Part Eleven: What Needs to Change

The hard conversations that follow from this case involve at least four distinct institutional failures.

The Restricted Area Permit system, designed precisely to prevent unrestricted foreign access to sensitive border states, failed completely. Whether through administrative negligence, local complicity, or a systemic lack of coordination between state and central authorities, seven foreign nationals moved through a restricted zone without the required documentation and nobody stopped them.

The India-Myanmar border management structure — underfunded, undermanned, and operating in genuinely difficult terrain — is not equal to the threat it faces. With barely 10 per cent of planned fencing in place and the Free Movement Regime’s suspension only partially enforced, the physical border remains, as it has long been described, more of a geographical line than a security barrier.

The intelligence architecture for the Northeast needs urgent examination. The gap between the Chief Minister’s public warning in 2025 and the NIA’s operational response in 2026 suggests that information is not moving fast enough, or is not being acted on with sufficient urgency, between state-level observations and federal enforcement.

And finally, India needs a clearer public doctrine on foreign mercenary activity on its territory. The VanDyke case is, by most accounts, the first time Western military veterans have been charged under the UAPA. That it took this long, and this specific a set of facts, to trigger that response suggests the legal and intelligence frameworks for identifying and responding to foreign mercenary operations in India are still being constructed.

Afterword: The Questions That Remain

Matthew VanDyke sits in NIA custody, his supporters in the West calling him a freedom fighter trapped in a misunderstanding. The Ukrainian government insists its nationals crossed an unmarked border by accident. The US Embassy declines comment.

Eight more Ukrainians are somewhere — in India, in Myanmar, or already home.

The drones are in Chin State.

And in New Delhi, investigators are going through the seized phones, tracing money, mapping networks, and pulling at threads that may lead them somewhere much larger than seven men at three airports.

The ghost route through Mizoram has been identified. The question now is whether India has the institutional will to close it — and whether it has the honesty to examine how it stayed open for so long.
