Military helicopters are either specifically built or converted for use by military forces. A military helicopter’s mission is a function of its design or conversion. The most frequent use of military helicopters is the transporting of troops, and transport helicopters can be adapted or converted to perform other missions such as combat search and rescue, medical evacuation, airborne command post, or even armed with weapons for attacking ground targets.
Specialized military helicopters are intended to conduct specific missions. Examples of dedicated military helicopters include attack, transport, observation, anti-submarine warfare helicopters, maritime multi-mission and rescue, training, and utility. All of these helicopters play an integral role in sea, land, and air operations of all modern militaries.
