In August 1988 , the British Army shot dead another three IRA men who were stalking a part-time Ulster Defence Regiment soldier whilst he was off-duty near Carrickmore . British intelligence sources claimed the men were involved in the Ballygawley bus bombing , which killed eight British soldiers and injured 28 , which resulted in the British Army changing its troop transportation methods in East Tyrone , switching from using unarmoured vehicular transport coaches on country roads , to ferrying them in and out of its bases in the district using helicopters
