Security team

A security team is a squad of security personnel. They are usually assigned aboard major Starfleet starships, and carry weapons such as phasers. Security team assignments included: guardduty, responding to and neutralizing threats to ship's security, and security or search operations on planetary surfaces and other off-ship locations.

Starfleet crewman Roger Lemli was a member of the security team aboard the USS Enterprise (NCC-1701). 

Captain Jean-Luc Picard ordered Worf to seal off deck 16 and post security teams on every access point when the Borg took over this deck. 

Aboard the USS Voyager in 2375, Neelix asked security to send a team to the mess hall after The Doctor started to develop a feedback loop in his holoprogramming.
