Handguns were an essential part of the World War I kit. They were used in close-quarters combat, and for officers and staff members who were in non-combatant roles but still needed to carry a weapon for self-defense. Handguns were also used for raiding enemy trenches, protecting officers, and enforcing discipline within military units. They were also useful in night-fighting and for other special operations like ambushes, and reconnaissance.handguns are easy to carry and quick to draw, which is important in the fast-paced, fluid situation of the battlefield. This makes them very useful in emergency situations and for close range combat.
