Thanks for the replies, mainly wanted to see if it was a rule mechanic or based on actual tables.See the reasoning(not saying I agree with it).
Wikepedea gives the MG42 effective range about 1050 metres to Brens 600 metres,but for MG42 it does not say whether it is when used in bipod or tripod.Guess is Wikepedia is correct for effective range in bipod mode but WW11 technical is for tripod,which would seem about right given that the Vickers Wikepedia quotes as about 2,500metres.
I know some rules just work on the basis if its in range you can shoot at it,guessed Matt had gone for effective,and he is right about close in terrain,one of the reasons most modern armies Assualt rifles are only range to 400metres (they may be even reducing it 200 with the newer weapons coming out)as this was generally the farthest apart you will find terrain in Europe(there was a idea that roops would not fire above that range anyway because of giving away their position)
Having fired a Lee Enfield at targets at 600yds, on a fairly open range,I was struggling to see the target never mind hit it.
Given the reasoning for aboves range by Matt then the BESA on british tanks possibly wants ammending according to one tank officer it could(generally for shooting at aircraft but if they saw german infantry what the hell) nearly match the MG42 for rate of fire(as could the Vickers K on which it was based)also in the desert(perhaps not relevant here)it could and was use by Tank crews to suppress german anti-tanks guns at very long ranges .
