What is the standard ammunition for the M110 SASS?

• A. 5.56mm x 45mm
• B. 7.62mm x 51mm
• C. 7.62mm x 54mm
• D. 9mm x 19mm

Answer: (B)

The M110 Semi-Automatic Sniper System (SASS) is designed to utilize the 7.62mm x 51mm cartridge, which is a standard NATO caliber commonly used in sniping and designated marksman rifles. This cartridge is favored for its balance of range, accuracy, and stopping power, making it suitable for various combat situations, including engaging targets at extended distances. The choice of this caliber allows the M110 to take advantage of the enhanced ballistic performance and terminal effectiveness on target, which are essential for a sniper's role.

The other options do not fit the specifications of the M110 SASS. The 5.56mm x 45mm is typically associated with lighter firearms and is not suited for the same engagement ranges as the 7.62mm cartridge. The 7.62mm x 54mm is a Russian cartridge not used in NATO-standard weapons, and the 9mm x 19mm is primarily used in sidearms and submachine guns, making it impractical for a sniper rifle designed for precision engagement at longer ranges. Thus, the selection of the 7.62mm x 51mm cartridge is a critical factor in the operational capabilities of the M110 SASS.
