Figure 5-1 Principles of rocket propulsion 5-2

(1) Antipersonnel rockets contain a filler of fin-stabilized steel fragments called flechettes.

They are employed against enemy personnel and light materiel.

(2) High-explosive rockets contain a filler of high explosive for blast, fragmentation, mining or demolition effect. The high-explosive antitank (HEAT) rocket, which contains a filler consisting of a shaped charge of Composition B or other high explosive, is used for penetration of armored targets.

(3) Chemical rockets contain a chemical agent and a burster to disperse the agent at the target. 'The chemical agent may be a gas for producing a toxic or harassing effect, an incendiary or a combination of these.

(4) Smoke rockets contain a filler of white phosphorus which produces smoke for screening and signaling.

(5) Spotting (red/yellow marker) rockets contain colored dye pellets and are used as target markers.

(6) Generally, practice rockets are assembled with completely inert warheads and dummy fuzes. However, warheads for large ground-to-ground practice rockets contain spotting charges and MT fuzes. All practice rockets are assembled with motors which contain the same propelling charge and igniter as the service rocket. Drill rockets, designed for training in service of the piece, are completely inert, both warhead and motor.
