Armory officer
Armory officers were those Starfleet personnel that commanded the weapons storage and operations facilities aboard a Federation starship, starbase, or outpost. This job was part of the oversight of the operations division.

In the early days of Starfleet, there were no formal security commands set up on exploration vessels (such as the  ), so the armory officer was often in charge of both tactical station functions and those of shipboard security. Many early policies of Starfleet security and tactical weaponry procedures were set in these early missions (such as the establishment of automatic tactical alert protocols coordinated by the ship's computer, devised by Armory Officer Malcolm Reed of Enterprise). The terms "armory officer" and "tactical officer" were used interchangeably, as the two jobs were occupied by the same person. () As of 2151, Reed's parents Stuart and Mary weren't aware of his status as armory officer, something both  and Jonathan Archer found odd. ()

The involvement of armory personnel in security operations lessened as MACO troops were assigned to Starfleet vessels during and after the Xindi conflict of the 2150s. Some functions of this department, in later years, evolved into the modern Starfleet Security department, where many of the same roles played in the Earth Starfleet were assigned to the position of security chief – which was sometimes occupied by the same individual who served as chief tactical officer.

Technological aptitude was within the purview of the armory officer's skill base, including perfecting a force field's particle density, building phase cannons from scratch, possessing knowledge of demolitions, and repairing relays with a hyperspanner. () By the 24th century, one security chief/chief tactical officer had such skill to develop unimatrix shielding. ()
