More than three decades after three Provisional IRA members were killed in a 1991 Special Air Service ambush in County Tyrone, fresh legal battles continue over the operation’s planning, bringing former British Prime Minister John Major into public focus over the military chain of command.
The lethal clash in the village of Coagh on 3 June 1991 remains one of the most controversial operations of the Troubles. Three members of the IRA’s East Tyrone Brigade—Michael Ryan, Lawrence McNally, and 22-year-old Tony Doris—died when British soldiers opened fire on a red Vauxhall Cavalier as the unit prepared to launch an ambush against a member of the Ulster Defence Regiment.
Decades later, the officer who planned the operation, speaking anonymously under the name David
on a podcast produced by The Independent, has detailed the intricate mechanics of the ambush and the political approvals behind it. The former major revealed that the chain of command for such high-risk missions extended past military generals and police chiefs directly to government leaders.
Inside the 1991 Ambush Plan in Coagh
The operation was constructed around a high-risk decoy strategy. British intelligence, which had deeply penetrated the IRA, learned that the paramilitary unit intended to shoot a local security force member as he waited for a ride to work. Security forces removed the intended target and replaced him with an SAS soldier of similar build, dressed to match his clothes, who stood waiting in Hanover Square.
The substitute volunteer put his life on the line, literally,
according to the planning officer. Hidden nearby were about a dozen soldiers poised to make arrests, supported by a heavy cover group concealed inside a flatbed builders’ lorry carrying scaffolding. A side of the lorry was rigged to drop in seconds, giving soldiers a clear field of fire across the square.
After an initial postponement on 31 May, the operation proceeded on Monday, 3 June 1991. Shortly before 7:30 a.m., an observation post spotted the red Vauxhall Cavalier entering Coagh with three men inside. As the car stopped beside the decoy, a passenger in the back seat rose and pointed an AK-type assault rifle directly at the undercover soldier.

The decoy threw himself backward over a wall as the scaffolding lorry dropped. The entire shooting incident took probably less than two seconds,
according to the former major. The car lurched forward and crashed into a parked vehicle, while the remaining armed occupants emerged and were shot dead. An inquest held in 2024 established that driver Tony Doris was unarmed and that no member of the IRA unit fired a weapon during the encounter, though two AK-type rifles were subsequently recovered.

The Dual-Key Chain of Command and Political Oversight
Reflecting on the authorization process, the former planning officer explained that ambush plans required a strict dual-key approval system involving both civilian police and military hierarchies. The Royal Ulster Constabulary chain of command ran to the chief constable, while the military chain extended to the commander of land forces, a two-star general.
When asked if the chain reached elected officials, the former soldier confirmed that the Secretary of State for Northern Ireland, Peter Brooke, and the prime minister at the time, John Major, sat at the apex of authority.
The purpose was to arrest terrorists in the act of committing a serious offence, The risk was that people were going to get hurt. Everyone knew that.

Inquest Validates Soldiers but Criticizes Operation Design
The legal fallout from the Coagh killings culminated in a lengthy inquest that delivered its conclusions in April 2024. Mr Justice Humphreys issued complex findings that validated the actions of the individual soldiers while sharply criticizing the operation’s design. The coroner ruled that the soldiers genuinely believed lives were in immediate danger and were justified in opening fire.
Furthermore, the inquest found that the operation was not planned in a manner which minimised to the greatest extent possible the need for recourse to lethal force
. That conclusion reinforced long-standing allegations that certain special forces missions functioned effectively as shoot-to-kill operations, a characterization former planners strongly reject.
Courts Reject Legal Challenges over Tony Doris Death
The central battleground in recent litigation has focused on Tony Doris, the driver who was proved to be unarmed. Legal representatives for the Doris family argued that Soldier B used excessive force by firing eight rounds at the driver. However, the coroner determined that the soldier could not have known Doris was unarmed and was entitled to view all three car occupants as an immediate collective threat.
Following the 2024 inquest, the legal challenges pursued by the Doris family faced multiple setbacks in higher courts. In October 2025, a court refused permission for a judicial review of the coroner’s findings, with the judge ruling the application utterly divorced from reality
regarding the pressure faced by the soldiers. The case then advanced to the Northern Ireland Court of Appeal.
In April, Lady Chief Justice Dame Siobhan Keegan dismissed the appeal, ruling that Mr Doris was part of the threat to life in this fast-moving situation
. Despite the dismissal, the legal fight persists as family members lodge a fresh application to the Supreme Court while debates over military accountability and allegations of legal pressure on veterans continue.
