Abstract:

The M-5 subsystem provides the aviation commander with a weapon which partially fills the gap between the 7.62mm machine gun and the 2.75-in. folding fin aerial rocket FFAR. It was most effective against personnel in the the open but it was also effective against sampans, thatched huts, ammunition stroage areas, and weapon positions without overhead cover. It provided suppressive fires up to 1200 meters when employed in areas other than dense jungle. In addition, it was capable of neutralization and destructive fires against soft targets within 700 meters. The M-5 was not effective when immediate reaction was required escort missions because of the time delay created by the low muzzle velocity of the projectile. Because of sighting limitations, close-in fires could not be provided safely at ranges over 700 meters unless firing passes were parallel to the front line of friendly ground forces. The M-5 subsystem, although evaluated on armed UH-1Bs, is considered a suitable weapon for troop transport helicopters. The present authorization of two M-5 subsystems per airmobile company should be increased to six, three mounted on UH-1B helicopters of the armed platoon, one each on a UH-1D of thr two transport platoons, and one held as a backup.
