The SG-43 Goryunov, a Soviet medium machine gun that was a replacement for the older M1910 Maxim.
Air cooled, and the heavy barrel could be easily changed.
Capable of 500 to 700 rounds per minute, and effective range of over a kilometre.
It was used in armoured vehicles, wheeled mounts (often with a gun shield) and on tripods (often in an AA role).
I guess the wheeled mount could be helpful...but I wonder how easy it would be over rough terrain (like scambling up a steep slope). Looks heavy.
Yes, this was a deliberate design consideration, to reduce the work for the GM. And it is in the rules.
FOW would have been nice, as well as simultaneous moves, but they entail so much calculation and time.
I don't want the campaign to become an unwelcome chore (for me), and have it fizzle out like many campaigns do.
Much like a traditional board game, both sides take turns and can see all the counters.
I mentally justified this by considering that the abstracted ground and aerial recon units are doing their job well.
