[quote=]UBC[ McNite]lol u got an idea about the recoil of 30mm cartridges? In WWI they were using 20mm single shot guns against tanks, but only few soldiers dared to use them due to the danger of breaking your shoulder :lol:
U can do a lot with good recoil brakes but i doubt that any infantry based gun you can actually carry will ever get the penetration energy needed for heavy armour.

The average recoil of the GAU-8 Avenger is 45 kN, probably enough to shoot you straight across the map if you try to use it, but all you need is some counterweight beeing shot into the opposite direction to compensate, so gluing together two GAUs with one shooting backwards would negate any recoil… but might cause some Friendly Fire incidents
