Most M16 and M4-style weapons issued are capable of semi-automatic fire and 3-round burst. The burst-fire mechanism utilizes a three-part automatic sear that fires up to three rounds for each pull of the trigger. It is non-resetting, meaning that if a soldier fires a two-round burst and releases the trigger, he will encounter a single round fired the next burst. In theory, burst-fire mechanisms allow ammunition conservation for troops with limited training and combat experience, at the cost of a very poor trigger pull. They also tend to limit the weapon's effectiveness when used in suppression, ambush situations, and close-quarters combat.
