M-1 Garand
The M-1 Garand was the main rifle used by American soldiers. It had a clip that held 8 bullets, and it made that loud 'ping' when you ran out of ammo. It was used from 1936 all the way until 1957.
'I shot 8 enemies, then that damn 'ping' echoed across the battlefield.', Soldier Doe, 1943
'The Garand was my best friend in the war. It had that annoying 'ping,' but it never failed me.', Private Brown, 1945
'That clip made a 'ping' that was louder than my mom’s scream.', Private Green, 1950
