I tested it and the Greyhound loses to a 222 head on, most of the time. Greyhound has a shit gun, shit armor, and extremely overpriced.
Buff it's main gun, armor, and make it worth its price and CP timing.
really? didnt the m8 had a 3,7cm gun? its funny how a vehicle can go from most powerfull light vehicle (vcoh) to loses to a paper vehicle (coh2)
