Plan A

This is a set of wargame rules intended to simulate actions between about one GF regiment equivalent a side, supported by divisional or even orbital forces where they would be available. It is possible to fight battles involving up to divisional size if you have enough players and time.

Scale: The smallest separately represented unit is the platoon or troop. This is shown on the tabletop by a cardboard base of the appropriate size, on which a suitable number of 1/300 or 1/900 scale models are mounted – the exact number per base can be varied to meet your own taste and financial resources.

It is even (just) possible to use 15mm or 10mm models – though the large size of the figures tends to distort player’s perceptions of the scale of operations – so I don't recommend it.
