R3 T20 

A very fast and nimble italian anti air, which was made popular in the MMO War Thunder because of players with tunnel vision that are unable to spot and counter it. Their primary complaint is that it's "too unrealistic" when in reality some R3s were fitted with stabilizers and night vision too.

Average WT Player: "Gaijin fix the R3 T20! It's OP!"
Actually good WT Player "Shut up and git gud"
