There were 28 Troubles-related deaths in February 1972.
As far as I can make out;
Five British Army were killed by the (Provisional) IRA. Two off-duty members of the Ulster Defence Regiment were also killed by IRA.
Seven members of IRA were killed. One was shot by the British Army. The others died in premature explosions, two in a single incident near Glenavy and four while transporting a bomb in East Belfast.
Six Catholic civilians died. One Tommy McElwaine was shot by a British Army sniper at Ballymurphy. He was known vaguely to me. Two were killed by loyalist gangs. The other three by IRA “in crossfire”.
Another civilian, an Englishman, a Walter Mitty character was shot dead by IRA in South Armagh.
Seven people, a British Parachute Regiment chaplain (Catholic) and six civilian canteen workers were killed by the Official IRA in an explosion at Para Headquarters in Aldershot, England. This was a direct reprisal for Bloody Sunday, which occurred a few weeks earlier.
