While Security officers handle internal threats, crime, and enforcing rules, Tactical handles external threats. They specialise in both ground and space combat, weaponry, and strategy - some even work as part of squadrons that can expand the combat capabilities of a ship. These officers are highly trained combatants and are responsible for the combat readiness of others in turn, with there being Tactical officers dedicated to training other crew.
Tactical officers handle the manning of a ship's weapons, from phasers and torpedoes to any additional assets. They can monitor and redivert shields, handle threat assessments, and provide combat strategies - such as deciding on attack patterns and evasive manoeuvres that the flight control officer can carry out. Some tacticians even work on a larger scale, learning to co-ordinate multiple ships. In away missions these officers work closely with Security to ensure that crew members get home safely.
Armourers maintain, supply, and repair weaponry for use on away missions. They are in charge of checking up on weapons throughout the starbase and ensuring that they are safe and ready for use if required. Maintenance and repairs of phasers and any other hand-held weapons is performed by them. When required, combat armour or EV suits are distributed by them, with the armourer ensuring the correct fit and functionality of the suit.
While Away Team Coordinators are in charge of the mission overall, Away Team Tacticians work to address any aspect that might require weaponry or have the possibility of combat emerging. They can plan anything from raids on an enemy ship to ground assaults, referring to data and schematics to ensure the best approach is taken. They provide expertise in stealth, combat, and mission strategy.
In combat scenarios, analysts work in real-time to assess the strengths, weaknesses, and capabilities of opposing vessels. They use data from sensors to interpret information on the enemy's movements, technology, and strategies, which in turn is used to create defensive strategies and counter-attacks. They can analyse battles after they have finished to analyse what could have been done differently and how to improve.
Combat instructors can work to teach close-quarters combat, the use of weaponry, or both. It is their job to ensure that all members of the crew, including those who do may not often face combat scenarios, are ready if needs be. They can teach different martial arts, help people to improve their aim, and even teach tactics, patrols, and land navigation. For civilians who live aboard Starfleet vessels, they can also teach them basic self defence.
These are highly trained professionals who design, handle, and dispose of any form of explosive materials. Their role can lead them to work in numerous scenarios: in dangerous away missions they can create and detonate their own explosives as breach charges, they can render unexploded ordnance or improvised explosive devices safe, can teach civilians about safe demolition techniques for the likes of mining, and can advise on the safe handling and storage of explosives.
Using Peregrine-class fighters as individual attack crafts, flight squadron pilots work in tandem to carry out offensive manoeuvres against an enemy. They can target specific sites for attack (e.g. engines,) draw enemy fire away from a ship or starbase, and help to even the odds against multiple attackers. Outside of combat they may use their crafts for reconnaissance, transport, flying drills, and advanced manoeuvres.
Phaser specialists are crew whose expertise is focused on the maintenance, operation, and application of phaser weapons systems. Some officers split their expertise into ground or space combat respectively. Ground phaser specialists can work on the maintenance of phasers and rifles alongside the armourer, and can use these tactically in the field. In space combat, they work to calibrate and deploy phaser arrays and cannons.
Torpedo specialists have expertise in the use of torpedoes and mines in space combat. They are capable of building torpedoes safely if required, and ensure their correct storage under health and safety rules when handling anything from photon to gravimetric types. to In combat they can advise on which types of torpedo would be most suitable and are trained not only in launching torpedoes, but in manually loading and maintaining the torpedo tubes.
