Which mortar has a system weight of 121.5 pounds in three loads and a range of 70 to 4,737 meters?

• A. M224 - 60mm Mortar
• B. M252 - new system
• C. M29A1 - 81mm Mortar
• D. M777 - 155mm Howitzer

Answer: (C)

Mortar identification hinges on matching both weight and range to the known profiles of each system. A system weight of 121.5 pounds in three loads points to the 81mm mortar family, and the M29A1 is the standard model in that class whose three-load configuration is around that total. Its published range reaches up to about 4,737 meters, which aligns with the given range. The 60mm mortar (M224) is lighter and typically doesn’t reach that far, so it doesn’t fit the weight and upper-range figure. The 155mm howitzer (M777) is much heavier and has a far longer range than 4,737 meters, so it’s not a match. The newer M252 system exists in the same broad class but does not align precisely with the 121.5-pound three-load weight and the 4,737-meter maximum given here. Therefore, the 81mm M29A1 mortar best matches both numbers.
