What about the Stuka? that thing is murder vs infantry and is deadly accurate and with skill can be landed on opponent's retreat paths...
The stuka is too accurate for it's own good when fighting snipers. Good players won't retreat but simply lolsprint sideways in a random direction. Missing with a stuka means you have to wait ~120 seconds to fire again, youre better of firing at support weapons to ensure kills than to pray for a bad opponent
