Troops Out Movement ( TOM ) is an organisation formed in the UK in 1973 following the attacks by the British Army on the minority Catholic/Nationalist populations , particularly the murders of unarmed civilians in Derry and Belfast by British paratroopers . The single aims were to secure the withdrawal of British troops from Ireland and self-determination for the Irish people as a whole . This required other demands such as the demilitarisation of the local police and paramilitary police support ( the B Specials ) as well as opposition to UK Government policies that maintained discrimination against Catholic people in areas such as elections , housing , education , cultural pursuits , jobs and social welfare . This led TOM to seek partnerships and joint working with like-minded organisations in the UK , Ireland and internationally
