The Sniper Rile System-56M, also known as the SRS-56M (Sniper Rifle System-56 Multirole), was an anti-personnel and anti-matériel rifle used by the United Nations Space Command. Designed as a lighter alternative to anti-matériel rifles using the 14.5x114mm round, but heavier than the 11.4x90mm round. Suitable for both anti-matériel and anti-personnel roles, the SRS-56M was widely used by the Marines and Army, and was fully compatible with SOPMOD attachments.
