What is the minimum depth of a fighting hole to protect against tank actions?

The minimum depth of a fighting hole to effectively protect against tank actions is 2 feet. This depth provides sufficient cover to shield personnel from the effects of small explosive forces, such as shrapnel or fragments generated by tank ammunition and other explosive devices. The key to a fighting hole's effectiveness lies not just in its depth, but in its ability to absorb and deflect incoming rounds and to provide a secure position from which Marines can operate.

A fighting hole that is at least 2 feet deep allows for effective concealment and minimizes the risk from enemy fire, particularly in armored confrontations. While a shallower hole may provide limited protection, it would typically not be sufficient to defend against the direct fire from armored vehicles. Deeper options may offer additional safety but are not always necessary for basic protection.

In combat situations, ensuring that the fighting hole meets or exceeds this minimum depth is crucial for maintaining the survivability and effectiveness of the unit engaged in operations. This standard reflects the tactical considerations that are vital in battlefield environments, especially when facing armored threats.
