Medium tank (Red Alert 1)

Great World War II
The medium tank was first implemented during the Great World War II to counter the ever increasing hordes of Soviet armor. Although the Soviet's lightest tank was still stronger than this tank, it did even the odds somewhat in that the medium tank could be far better mass produced than any Soviet tank, as it was significantly cheaper. Unfortunately, it was outclassed by the Heavy Tank. The Heavy Tank] was as fast as it, but mounted two 105 mm Cannons, and therefore, twice the firepower. As mentioned, however, Medium tanks were much cheaper.

An improved version of of this tank, the Grizzaly Tank was developed before the Great World War III.

Counters
As mentioned, Rocket Infantry were effective, although their lack of speed meant it could be difficult for a target to not be squished by a Medium Tank - care was needed. Furthermore, Medium tanks could be targeted by Recon bikes or Light Tanks in groups, at which point a Medium tank would fail. But in general, it was highly effective against enemy armored vehicles, and was a match for a flame tank one-on-one.
