Flak trooper (Red Alert 2)

The Flak Trooper was a Soviet soldier during Great World War III. They were mostly used against the Allies' aircraft.

Uses
Flak Troopers could easily shoot down Ospreys, Harriers, Black Eagles, and Nighthawks, unless they were eliminated first. They could kill infantry, mostly just GIs or Engineers, with their Flak cannons, but they were usually killed first. Against light vehicles, they could take them out, but their low armor meant they could die first, and probably would.

Counters
Flak troopers had low armor, and thus, Nighthawks could usually kill them before they were shot down. All allied infantry could take them out quickly. Vehicles good against infantry, such as the Prism Tank or the Mirage Tank, would take them out before they posed a threat.

Thus, it is clear that Flak Troopers only excelled against aircraft.
