The Grumble is a Soviet stolen tech unit acquired by infiltrating an Allied Tech Center and Construction Yard. Arguably one of the most powerful anti-air weapons in the war, it can easily bring down enemy aircraft in its way.
However, one has to take note that the Grumble must be deployed first before it can fire and it cannot attack aircraft that flies too close.
The Grumble is the Soviet response to the continuously expanding Allied air force, available once Allied technology has been carefully researched by Soviet spies. With a set of massive rocket launchers, the Grumble is capable of eliminating any type of aircraft at great ranges when deployed.
The Grumble has no means of defending itself against ground targets so it requires support from other units. It also has a minimum range that enemy aircraft can approach and stay safe in so remember to create your Grumble defense line wisely and don't leave any "dead zones".
Being the most powerful anti-air unit in the game, the Grumble's construction prerequisites are correspondingly demanding. The Soviet commanders must let their Saboteurs infiltrate the Allied Construction Yard and Tech Center from at least one Allied enemy. However, it is worth noting that oncec a Grumble is built,it could not use the missile to intercept the air unit but the Soviet commander should move it to the right position (and the expanded Grumble occupied two grids) so it can play its air defense capabilities.
The missiles fired by Grumble can destroy a heavy aircraft with just two hits, but its biggest drawback is the poor maneuverability, even cannot target aircraft that flies directly-above the Grumble itself, and the lack of ground unit resistance. If a defenseless Grumble is attacked by an anti-armor units, it is quite difficult to transfer it to a safe area in time because of its slow speed. Due to this feature limitation, Grumble is generally only used for base defense.
- In the Revolution Challenge, the enemy bases are protected by a limited number of Grumbles.
- The Grumble is based upon the real-life S-300 (SA-10 "Grumble") heavy surface-to-air missile launcher that was used by the Soviet Union.
