Atomic Warlords got themselves some of the American forces from All Quiet on the Martian Front and gives you their thoughts on them in this review article.
From the post:
All Quiet on the Martian Front was just released by the nice folk over at Alien Dungeon. It is a 15mm scale tactical game of the Martian invasion early 20th century. The “current” game year is 1914 and the Martians control a large part of the globe. I backed it on Kickstarter just over a year ago and finally the big box arrived containing about 2/3 of the initial releases.
