In the United States, state police are a police body unique to each U.S. state, having statewide authority to conduct law enforcement activities and criminal investigations. In general, they perform functions outside the jurisdiction of the county sheriff (Vermont being a notable exception), such as enforcing traffic laws on state highways and interstate expressways, overseeing the security of the state capitol complex, protecting the governor, training new officers for local police forces too small to operate an academy, providing technological and scientific services, supporting local police and helping to coordinate multi-jurisdictional task force activity in serious or complicated cases in those states that grant full police powers statewide. A general trend has been to bring all of these agencies under a state Department of Public Safety. Additionally, they may serve under different state departments such as the Highway Patrol under the state Department of Transportation and the Marine patrol under the state Department of Natural Resources. Twenty-two U.S. states use the term “State Police”, eighteen use the term “Highway Patrol”, and seven use the term “State Patrol”.
A fireteam is a small military sub-subunit of infantry designed to optimize “bounding overwatch” and “fire and movement” tactical doctrine in combat. Depending on mission requirements, a typical fireteam consists of 4 or fewer members; a grenadier, anautomatic rifleman, a rifleman, and a designated team leader; the role of each fireteam leader is to ensure the fireteam operates as a cohesive unit. Two or three fireteams are organized into a squad or section in coordinated operations, which is led by asquad leader.
