British Expeditionary Force (BEF) France 1940
Just the barest outline of a battle group at this stage
Back row: Pendraken Matilda IIs, Pithead A13, Minifigs 2pdr ATG
Front row: Pithead Matilda Is, Pendraken Vickers Mk VI C, and Pithead Mk VI Bs
I can get away with using infantry, vehicles and 25pdrs from by 1944 forces, which will certainly be close enough to start with!
Most are painted with Vallejo Bronze Green, with highlights of this mixed with increasing amounts of pale sand.
