Figure 2-50. HE warheads for the 2.75-inch rocket.
The M261 is an HE, multi-purpose submunition (MPSM) warhead. An M261 warhead is shown in Figure 2-51. It
is designed for use against personnel, material, and light armor. This item is issued as a complete round
consisting of a warhead, a fuze, and a rocket motor. The warhead has a plastic nose cone, a hollow extruded-
aluminum body, and a metal base that is attached to the body with shear pins. The M261 warhead carries nine
M73 submunitions, which are independently fuzed with ram-air-decelerator (RAD) fuzes. The warhead itself uses
an ET fuze, which is energized by the aircraft, and, after launch, ejects the payload from the base of the warhead.
The color code for the M261 is an olive-drab body with one yellow band and yellow markings. Its DODIC is H464.
The WDU-4A/A, also shown in Figure 2-51, is another antipersonnel warhead for the 2.75-inch rocket. This item
is issued as a complete round. The warhead has a plastic nose cone, a hollow extruded-aluminum body, and a
BD fuze. It contains 2,200 flechettes, which are expelled through its nose. The color code for the WDU-4A/A is
an olive-drab body with white markings. Its DODIC is H459.
The M156, shown in Figure 2-52, is a WP smoke warhead. It is issued under four different DODICs, depending
on fuze and motor combinations. This warhead is used to provide smoke for target-marking and incendiary
purposes. It can be used with PD or PRX fuzing. The color code for the M156 warhead is a light-green body with
one yellow band and yellow markings. The DODICs for the M156 are H472, H519, H486, and H593.
