TOS, again, calm down. Let this guy go his way. You ranting is reserved for us. . .
We do not have to discuss that WWII SMGs were different from nowadays SMGs. Or buildings in WWII Europe (you can still place buildings closer together). And we do not have to compare BFG to 40K. . . if someone likes 40K, then stay with it and leave us guys alone!
I shoot 357 or .54 (blackpowder target pistol) at 25 meters into a 7 to 8 on the sheet (that ist about 8 inches diameter, enough for a solid kill). I do this standing, with two hands. I guess there are better shots than me in this forum.
I will not discuss 12 inches ranges for pistols. That is ridiculous. They deserve the same range as the SMG. They are, in fact, the same weapon, with a lower ROF and missing a stock.
But I would like to give SMGs 2D6 damage dice. Pistols can have 1D6. And do not give the SMGs an extra suppression rule, to keep things fast. SMGs should be deadly at short range. Leave the extra suppression rule as a trait for troops.
An extra CC D6 against other infantry models ist a good rule.
I like the 4 inch range. That is playable and with the FZ more than enough range. Let the FZ still be 6 inches, this way you are more likely to hit other friendly squads and the game is simple.
So our SMGs could be:
SMG, range 4'', 2D6 damage dice, no extreme range, no setup, suppression on 2+, special rule: Add 1D6 against other infantry models in CC.
Our bolt action could be:
Bold action rifle, range 20'', 1D6 damage die, extreme range, no setup, suppression on 3+.
Do we agree on this as a beginnig so far?
We need a theatre and a year. I would take Unternehmen Barbarossa (one of the biggest military actions in history), mean eastern front summer 41. Then we can evolve to 42 and 43 (with Stanlingrad and the the decision of the war, Kursk), or take a look a 39 and 40 and Africa 41.
We can lock on infantry combat and include a bit tank warfare. The war of 41 means that tanks are not so heavy as later in the war.
