The reaction control thrusters are the standard thrusters used by the Federation for low-velocity propulsion, station-keeping and maneuvering control in space.
In 2367, in an attempt to escape from a Promellian battle cruiser surrounded by aceton assimilators, Jean-Luc Picard used only two of the USS Enterprise-D's RCS thrusters to maneuver the vessel through the remains of Orelious IX. (TNG: "Booby Trap")
In 2369 Deep Space 9 was moved from the orbit of Bajor to the mouth of the Bajoran wormhole with six of the stations RCS thrusters. A subspace field was used to reduce the stations inertial mass to shorten the travel time from two moths to some minutes. (DS9: "Emissary") Another way of getting more velocity from RCS thrusters is to accelerate the deuterium feed and burn them beyond safety limits.(VOY: "The Cloud")
In order to conduct an emergency shutdown of all RCS thrusters, all deuterium from the RCS system must be vented out. (VOY: "The Cloud")
Starfleet regulations state that only thrusters are allowed for propulsion inside a space dock (Star Trek VI: The Undiscovered Country)
Background
According to Star Trek: The Next Generation Technical Manual, although serving the same function, the propulsive exhaust production behind the RCS thruster seems to vary slightly, depending on the size of the craft.
Starships have apparently primary and auxiliary thrusters. The primary thrusters are powered by a gas-fusion reaction chamber. It uses deuterium fuel from fuel tanks that in turn are fed from the ships main deuterium tank. Exhaust is delivered through a field trap into the vectored thrust nozzles visible from the outside. Auxiliary thrusters have no tanks or fieldtraps, and are powered by a microfusion chamber. The generated thrust is considerably lower.
Shuttlecraft, escape pods, work bees and some probes are told to also use microfusion thrusters. In the Star Trek: Deep Space Nine Technical Manual, the Defiant's lifeboats are said to use something called impulse microthrusters and the microtorpedoes in turn use a miniature fusion thruster for propulsion. Whether these are both synonymous with a microfusion thruster is unclear. Shuttlepods in turn use hot gas thrusters, powered apparently by power cells rather than a fuel tank.
It is not known what type of RCS thrusters Federation space stations use, but it is noted in the Star Trek: Deep Space Nine Technical Manual that they are somewhat similar to what the Cardassian stations use. Deuterium fuel is fed into a protean-cycle fusion reaction chamber to produce the exhaust to the thrustnozzles. This seems to differ from a starship thruster in the sense that it is designed to create a low thrust.
