Since the thread got resurrected.I was in the British Army - they didn't give me the option of keeping my SLR, let alone the sterling smg and the browning 9mm they also trained me to use.
As a curiosity, was there a point when weapons were given out to troops leaving service? Did the US Army in the 1800's send the trooper off with a pistol or something? Did the Romans let their soldiers keep their sword and shield?
