Putting together my great-grandfather's army service, which began in 1926 when he enlisted as a "Boy" soldier, his service ends in 1947 with the following stamp: "Released to Class Z, Royal Army Reserve. Date: 3/10/47 (Class 'A' Release" But his Military History Sheet goes on to state "Z Reserve from 3/10/47 - 22/3/51" Could any one tell me what this means? Was he demobbed? Would he have had a choice to stay on? Also, what would he have been doing in the 'reserves' between '47 and '51? Would he have been back on civvy street then?
