Service rifle

The service rifle (also known as standard-issue rifle) of a given army or armed force is that which it issues as standard to its soldiers. In modern forces, this is typically a highly versatile and rugged assault rifle, battle rifle or carbine suitable for use in nearly all theatres and environments. Service rifles are also often selected for their upgradability (e.g., the addition of underslung grenade launchers, sights, flashlights, laser sights, etc.)
