- A Cosmonaut expresses his excitement about weightlessness
Cosmonauts are equipped with all the necessary life support equipment to survive in the vacuum and a jet pack like that used by Allied Rocketeers. They are armed with a laser cannon that is most effective against enemy infantry and vehicles.
- In Earthrise, Cosmonauts serve as the main infantry unit of both the player's Russian and the enemy Epsilon forces, replacing most infantry except the Engineer, Tesla Trooper, Desolator, Brute, Bloatick and Dunerider.
- In the Revolution Challenge, Cosmonauts are part of the enemy Soviet forces, spawn from the Rocket Launch Bays and attack the challengers' base.
