In the Autumn of 1916 the way troops were trained was changes. Previously new recruits were allocated to on on the existing regiments, but the new arrangement was to have Training Reserve Battalions and the men were only allocated to regiments when their training was complete. The picture here is the 20 Platoon, F Company, 22nd T.R.B. and was taken by L. L. Christmas, of St Albans. Most of the men in this photograph are wearing the General Service cap badge - but six in the middle of the 2nd row are wearing distinctive cap badges.
The second photo shows orderlies of the 23rd. T.R.B., also taken by L. L. Christmas.
