M67

[Tarranauha200]

Firstly the M67 moves its turret sideways and upwards too fast. (source)
Secondly the flamethrower range is way too low. (source) (source2)
Thirdly the flamethrower overheats very quicky. I dont have sources for the last one but very similar M132 can fire up to 32 seconds. I think that the fuel is ignited outside the barrel so it shouldt overheat it. Correct me if Im wrong.
