Many different types of ammunition were used by various countries during World War II. Some were bombs dropped from airplanes, bullets shot from different types of guns, and torpedoes shot from submarines.
Knives were used often in World War 2 for knocking off the enemy quietly, especially at night, so as not to advertise one's presence or position with something noisy like gunfire or grenades. Knives were also carried for hand-to-hand combat, as they were not subject to jamming or expenditure of ammo like firearms, and they were sometimes a soldier's last hope for survival. The British Sykes-Fairbairn commando dagger and the US Marine Ka-Bar are two of the more famous World War 2 combat knives, but there were many others. The Gurkha regiments were also infamous for their use of the khukri, a large knife well-suited for hacking and stabbing.
