In addition to the skills necessary to fly their missions, Commando Helicopter Force members are trained in small-arms use as well as tactics and survival fieldcraft. Being a naval unit that was directly tasked with supporting the Royal Marines, trainees are also schooled in shipboard and amphibious assault operations.
