In modern warfare, firearms are the standard weapon, but that doesn't mean knives don't have a place. Knives can be used for close-quarters combat, as a last resort weapon, or for utility purposes like opening doors or cutting through wire fences.
There are a variety of knives available to soldiers depending on the mission at hand. The most common type is the combat knife, which is designed for fighting in close quarters. These knives typically have a serrated edge and a strong point that can be used for thrusting or stabbing.
Utility knives are also popular in the military. These are smaller blades that can be used for tasks like opening ration packets or cutting through barbed wire. Some utility knives even come with extra features like saws or bottle openers.
Last resort knives are just what they sound like - blades that are only to be used when all other options have been exhausted. These include small hideout blades that can be concealed on the body, and larger fixed-blade survival knives that can be used for self-defense or bushcrafting in an emergency situation.
So yes, while guns are the primary weapon of choice in modern warfare, there's still a place for good old fashioned knives.
