Vehicles in 6mm from Irregular may not be as detailed as those from GHQ but they are much cheaper and work great as targets.
Hallmark (sold by Magister Militum) have a range of 1:1200 ship models. A scale that fits nicely on a target card. I will be using these for refighting the early stages of the Battle of Britain; the kanalkampf when the Luftwaffe attacked shipping in the English Channel.
