The Tug Module is the smallest tug module in the game. It is not specially designed for certain payloads (such as the Gemini Service Module). It is useful for orbital adjustments of its ample supply of thruster propellant and rocket fuel. It is vital for docking as the main engines are very hard to turn the spacecraft with.
