"Special Ops Aviation: The men and machines of the elite units. By Patrick Allen. Many nations are developing and expanding the roles for their airborne, airmobile and commando forces, each requiring dedicated and specialized aviation support. As the military has turned to aviation, so have many of the world's para-public organizations like law enforcement, emergency medical support, fire fighting and mountain rescue. Interesting book shows lots of flight gear and aircraft. Excellent color photos showing lots of action!"
