APHE ordinance requires how many blocks of M112?

The correct amount of M112 blocks required for Armor-Piercing High-Explosive (APHE) ordnance is two blocks. This requirement is based on the specific explosive configuration needed to achieve the desired detonation characteristics and effectiveness of the ordnance.

In handling ordnance, especially those designed for armor-piercing capabilities, precise amounts of explosive material are critical for ensuring the ordnance functions as intended. Utilizing two blocks of M112 ensures adequate energy for penetration and subsequent damage while maintaining safety and compliance with operational standards. The choice of explosive and its configuration is fundamental to the performance criteria set for APHE ordnance, which distinguishes it from other types that may require different amounts or configurations of explosive material.

In contrast, other options do not meet the established operational standards or the design specifications necessary for APHE to achieve its intended ballistic performance.
