Recruits wear field caps for the first six weeks of training. At the end of week 6 the recruits are tested on the parade square by performing drill and questioned on regimental history. If the recruits pass they are given the Parachute Regiment beret to wear. The beret will have a green backing behind the winged cap badge to illustrate the recruit has passed off the square, however, he has not passed P Company. Once the recruit has passed P Company the green backing can be removed from the beret.
Doesn't matter it won't look as smart as a Royal Anglian beret.........
Policy on this has changed a number of times over the years....pre-direct intake I'm pretty sure the blokes wore their parent Regt beret etc until passing P Coy, after that some of the old recruit photos I've seen show the lads wearing the beret without any backing, then at some stage the backing was brought in to denote recruit status.
During the mid 80's recruits went through a period of wearing the cnut cap right up to P Coy with shoulder flashes of red, blue, green to denote what stage of training they were in....best system imho....then the green backing was brought back in and has stayed.
Juniors used to wear a blue backing behind the badge.
