What I was "planning" was two campaigns, the first in 1942 during the battles in and around Volgograd (aka Stalingrad), and the second North Africa also in 1942-1943.
Second campaigns is more appreciated, coz at this time there are only 5 missions(from ~200) for the North Africa.
So using the M4 tank with a 75-mm, the Stuart and Lee/Grant tanks have been "build", many thanks for that, Oh sorry I forgot the British Matilda.
There are also "Valentine", "Churchill" and during next month M3"Honey", M4A1, "Universal Carrier", fuel-trucks are coming. But without mission these units have a small chance to take place in the game. M3"Honey" and "Universal cariers" will see the light in the mission "dust in the wind2", which will be based on the improvements from 33lima.
I believe I saw the Italian M13 tank for the North Africa campaign. For the Stalingrad battles- a new terrain may have to be mapped.
At this moment there is only one Italian tank. It is light tank L6/40. As my point, there is no need to make smth. really global like campaign. The best way to start is - making missions with current units, which in the future will be replaced on the new ones.
