30x30 is a bit small, but would do for a company or 2 if it is a "leg" battle. For a mechanised force it is a bit of a postage stamp really. It may do for a particular scenario that focusses on a small area of a city map (like the tractor factory in Stalingrad) perhaps.

You could increase battlefield depth a bit if the enemy is expected to use AFV, and also to allow for an artillery park to be deployed that's outside of HMG range of the defenders.

I use an 80x80 map size for battalion-sized core forces (generally 3 rifle coy, 1 tank coy) when I am using leg infantry supported by tanks. That gives a large enough space for manoeuvre without too long a trudge for the infantry, but if it were a snow battlefield or an impenetrable jungle I may want to reduce width to say 60 hexes or so.

I know that Don likes to play games on postage stamp maps, but that's not my particular preference. But the point of our version of the game is to provide the end user with choice. At the end of it all then it is down to personal preference, there is not really one "right way".
