Final answer:
HEAA rockets contain a high-explosive chemical compound designed to penetrate armor using a shaped charge that creates a high-speed jet of metal.
Step-by-step explanation:
The type of explosive contained inside an HEAA (High Explosive Anti Armor) rocket is typically a form of high-explosive chemical compound. HEAA rockets are designed to penetrate armor using a shaped charge, which focuses the energy of the explosion to a small point, creating a high-speed jet of metal that can breach the armor. The specific explosives used in these warheads could include RDX, HMX or a combination in a composition such as Composition B, though exact formulations are often classified.
