M113
The M113 is an American armored vehicle I'm widespread use by many foreign nations. The APC was first used during the Vietnam war by American forces and South Vietnamese ARVN forces. As of 2022 it still continues service in the military of the United States of America but it is slowly being phased out due to this tank becoming obsolete.
The M113 looks like a giant box on tracks, I wonder if the armor protect is that of a box!
