Modern use

The dagger is in military use as a close combat and ceremonial arm.

Many nations use the dagger pattern in the form of the bayonet. Daggers are commonly used as part of the insignias of elite military units or special forces, such as the US Army Special Operations Command, the US Army Special Forces, or the Commando Dagger patch for those who have completed the British All Arms Commando Course.
