Reaction control systems are capable of providing small amounts of thrust in any desired direction or combination of directions. An RCS is also capable of providing torque to allow control of rotation (roll, pitch, and yaw). [2] Reaction control systems often use combinations of large and small thrusters, to allow different levels of response.

"A reaction control system (RCS) is a subsystem of a spacecraft whose purpose is attitude control and steering by the use of thrusters". Attitude and Orbit control "An RCS system is capable of providing small amounts of thrust in any desired direction or combination of directions".
The R-4D is a small hypergolic rocket engine, originally designed by Marquardt Corporation for use as a reaction control system thruster on vehicles of the Apollo crewed Moon landing program. Aerojet Rocketdyne manufactures and markets modern versions of the R-4D. [1]
The air force's headquarters is located in Tirana and it operates three airbases: Tirana Air Base with the national Control and Reporting Centre, which reports to NATO's Integrated Air Defense System CAOC Torrejón in Spain, Kuçovë Air Base, and Lapraka Air Base, home to the government's transport helicopters.

The system was also used to push the spacecraft away from the spent second stage of the Titan II launch vehicle on first reaching orbit. The eight rotational control engines were mounted off the spacecraft's center of mass around the aft section of the Equipment Module, pointed at 90 degree positions up, down, left and right.
On January 18, 1965, the entire honors system was completely revised. In addition to establishing many new orders and medals, some pre-existing decorations were modified as well. The Order of the Red Star was expanded from one to three classes and a new medal was added.
Its name comes from the information path in the system: process inputs (e.g., voltage applied to an electric motor) have an effect on the process outputs (e.g., speed or torque of the motor), which is measured with sensors and processed by the controller; the result (the control signal) is "fed back" as input to the process, closing the loop.
