I picked up both the main expansion for the Great War boardgame, which features male and female MkIVs and German A7Vs, as well as German artillery, and the Whippet expansion, which I'll go ahead and assume needs no explanation.
In addition to the German artillery (105mm guns), I also picked up some British opposition (18pdrs). I'm easily amused, so having this gun in 28mm, 15mm and 6mm makes me smile. :D They come in the usual brown plastic for the Brits, and grey for the Germans. They have been undercoated in the following pictures.
Flames of War
Obviously, the primary reason for purchasing these models is to use them with the boardgame. However, my mate fancies getting into Flames of War's WWI expansion, and so I'll be working out how to use these guys for both systems before basing anybody. Obviously, in time I shall expand my collection beyond just the plastics so I have a broader range of poses - and some officers, too! Hopefully, in a few months, we'll get a game in.
