One AT Mines shell places very many mines in an area. I tested the Scorcher and found 8 mines at the area of impact. These are pretty powerful mines than can disable heavy armor with one hit. Is this realistic? Lets see... Powerful mines, perhaps equivalent to 10kg AT Mine. 10kg * 8 = 80kg mines in one shell? Not even close to realistic.
Lets compare that to a real life artillery projectile. How about the US M107 155mm projectile. Total wheight is 43.88kg. Explosive warhead is 6.6 - 7kg. How does one fit 80kg of mines in one of these shells? :D
This issue is important for balancing reasons becouse the AT Mine shell is not only unrealistic, it is also very overpowered, something I experienced yesterday on a warfare server where I was commanding OPFOR forces.
My proposal to fix both of these issues is to only include one AT mine per shell fired, but increase the ammount of shells carried by each artillery piece. This will make it slightly more difficult to use and it will take more time to deploy an effective minefield. It is also more realistic considering what kind of warhead the 155mm projectiles can deploy.
