Since Battlefront was good enough to give away the 3rd edition of the Flames of War rules, I picked up a copy. I'm seriously considering building a new army after Adepticon. My preference is a British armored company. Plastic Solider Company is releasing a Firefly kit soon, so that will certainly make a late war list very practical in terms of cost. Unfortunately there is little overlap between mid war and late war British equipment, so I will have to practically build a second army for mid-war.
I was considering building a 7th Armored list for late war, but there's a cool online briefing for Grenadier Guards. They can take American paras as allies in their lists plus can have up to two Fireflies per tank platoon. It wouldn't be too hard to do both since the only real difference would bee needing more Sherman V's for the Gaurds and more Cromwells for the 7th.
For mid-war I want to build something with lots of Crusader tanks. They just look so damn cool. I've read that they are overpriced currently, but I don't care.
