How many pounds of Composition B4 are used in the M1A2 Bangalore Torpedo?

The M1A2 Bangalore Torpedo is utilized primarily for clearing obstacles and breaching barbed wire or other fortifications. It is designed to be a lightweight, explosive device that can be effectively handled and deployed by infantry. The correct answer indicates that the Bangalore Torpedo contains 10 ½ pounds of Composition B, which is a mixture of RDX and TNT commonly used in military explosives due to its stability and effectiveness.

This quantity of Composition B allows the torpedo to provide the necessary explosive force for its intended purpose without making it overly cumbersome for transport and deployment by soldiers. This careful balance of weight and explosive capability is critical in ensuring that the device is both effective and user-friendly in combat situations.

In contrast, other choices represent weights that either exceed the practical deployment capabilities of the torpedo or are too low to provide the necessary explosive power for effective obstacle clearance.
