Which mortar configuration provides high-angle suppressive fire with a 60mm range of 3,500 meters and an 81mm range of 5,700 meters?

Which mortar configuration provides high-angle suppressive fire with a 60mm range of 3,500 meters and an 81mm range of 5,700 meters?

• A. 60mm Mortar
• B. 60/81mm Mortar
• C. 81mm Mortar
• D. 120mm Mortar

Answer: (B)

Combining two calibers in one mortar system gives the versatility to deliver high‑angle suppressive fire at both shorter and longer ranges. The numbers shown—60mm reaching about 3,500 meters and 81mm reaching about 5,700 meters—fit exactly a dual‑caliber setup, which lets a unit switch between lighter, quicker rounds for close support and heavier rounds for longer-range interdiction. This setup is ideal for suppressive fire because you can keep the enemy pinned with the closer, high‑arc fires while still reaching positions that are farther away with the longer‑range rounds, all from a single platform. A single 60mm or a single 81mm configuration wouldn’t provide both ranges, and a 120mm mortar is a different system with different capabilities.
