Tank Commander is a collectible card wargame covering tactical combat on the Eastern Front during WW2 designed by John Desch and Ulrich Blennemann and firsts published by Moments in History in 1996.
Each deck contains 60 cards, a small 56 page rule book (don't gasp -- you can grasp play concepts in seconds). Two decks are the minimum required for play. Six decks maximize the experience.
Each card, designed by Beth Queman, represents a vehicle, (tank, half-track, armored car, truck) infantry or calvary squad, AT gun and crew, special equipment (like a Panzerfaust), terrain type and special events. There are a total of 164 different card types in 3 different levels of rarity. There's some minor card errata (nothing serious) and a list of all types on Web-Grognards. Each card has a color picture, short description, and different numbers representing game factors.
