In support of this role, the battery provides FSTs to the Royal Navy when conducting training on a variety of gunnery ranges around the world.

It was tasked with providing FO teams to the Royal Marines, the Parachute Regiment; the ACE Mobile Force (Land) (AMF(L)) and the SBS.

The ship's weapons staff spent the next 24 hours going through their system, and discovered their radar had not locked onto the correct datum point, creating an error in firing equal to that calculated by the FO officer.

[2] FO teams called artillery fire and air strikes onto Argentine positions in support of every major British assault.

3 Commando Brigade conducted an amphibious landing to occupy the Al Faw Peninsula during Operation Telic, the 2003 invasion of Iraq.

On the first night of the operation the unit suffered its first deaths of the war when a US Marine helicopter crashed close to the Iraq Border.

[4] The battery is formed into a number of Fire Support Teams (FSTs), operating ashore or in advance of the Forward Edge of Battle Area, to observe and identify candidate targets, conduct preliminary Battle Damage Assessment, adjust fire or provide target illumination for laser guided weapons.

Personnel are trained in infiltration and exfiltration, covert observation, target identification and location, voice and data communications, adjusting gunfire from both afloat and ashore, and Forward Air Control (FAC) techniques.

As of July 2020, the battery began transitioning to the Colt Canada C8 rifles, similar to that of the UKSF and the Royal Marines adapting the Future Commando Force perception.
