Present arms is a two-part drill command used by many militaries and public safety professionals in the world as a sign of respect. It comes from the old British command "Arms to the present!"

Drill commands are generally used with a group that is marching, most often in military foot drills or in a marching band. Drill commands are usually heard in major events involving service personnel, reservists and veterans of a country's armed forces, and by extension, public security services and youth uniformed organizations.
