 At the outbreak of war the Antrim RGA had a strength of 607 all ranks, but as the war progressed and the likelihood of German attacks on the coast diminished, the Special Reserve's role of supplying and training reinforcement drafts for fighting units of the RGA took precedence.By August 1918 the unit had only 18 men on its books.After the Armistice with Germany all Special Reserve units were demobilised in 1919 and placed in suspended animation.
