That would be utterly ridiculous - you could be given a beach assault custon map for your meeter and have to deploy on deep water and so all drown or a huge map, a desert for your euro battle map, or have do deoploay your huge core on a 20x20 postage stamp map etc.

if you really wantto do that sort of thing - list out a a few suitabe map numbers and use a pack of cards to choose?
