Unfortunately, the Blitzkrieg book is the one I play from the most, and it was published before these cards became a Thing. So, I decided to make some of my own, having completely forgotten that the publishers have now made separate sets of cards available. For the cost of a few quid I could have saved myself a whole lot of effort. Hey-ho.
I've printed them with an image of the vehicle on one side, handy if you can't remember which model of SdKfz 251 is which. On the other side is the game-relevant information and a coloured background to distinguish the nationalities — khaki-brown for the British and grey for the Germans. The colours are mainly to make sorting them into their sets a bit easier.
NOTE: Unlike most of the printable game aids I make for my own gaming, I won't be making these available for download — there would be copyright issues with many of the images I've used for a start, not to mention that they'd be in direct competition with the Battlegroup card sets, and I like those guys. So, these ones are just for me.
