Which HMMWV vehicle is designed for both cargo and troop transport?

The M1123 is specifically designed as a variant of the HMMWV that serves dual purposes, accommodating both cargo and troop transport. This configuration makes the M1123 particularly versatile in military operations, allowing it to shuttle personnel along with essential gear or equipment to various locations on the battlefield. Its design incorporates a cargo area that can easily be adapted for different missions, whether that involves personnel seating or space for supplies, thereby enhancing operational efficiency.

The other variants, while having their own unique capabilities, do not focus on this dual-functionality as effectively as the M1123. For instance, the M1151 and M1152 are more oriented toward enhanced protection and are typically configured for troop transport but might not balance cargo capability to the same extent. The M1114 is primarily geared towards providing armor for troops, focusing less on cargo transportation. Therefore, the M1123 stands out for its ability to meet both troop and cargo transport requirements in various mission scenarios.
