Chitzkoi (Чицкой) is a Soviet cybernetic German Shepherd appearing in Red Alert expansion packs.
Apart from resistant armour plates, Chitzkoi is fitted with artificial muscles, allowing him to jump distances many times the ones a regular dog could cover. He is the closest friend of the Soviet super soldier Volkov, having undergone the same treatment.
Chitzkoi acts like a regular attack dog, except he can jump farther (scaling cliffs in the process) and is much, much more resistant to damage. During Let's Make A Steal, Chitzkoi may be killed without failing the mission.
Chitzkoi appears in version 2.0 in the Mental Omega mod. He is almost completely robotic and acts both as a regular attack dog and as a Terror drone (Red Alert 2), he is capable of latching and destroying land vehicles too. He is a special unit, available only in Campaign mode and only in some missions.
He appears also in version 3.0 of Mental Omega, with a slightly different look but with the same purpose. He is no longer a Campaign-exclusive unit, as he and Volkov are both hero units for the Russian subfaction.
