The first sheet is exactly enough cards for a 4-point force - a leader, four special characters, and four unit cards. The second sheet gives you the Reload, Turn Over, and Event cards, plus three more character and unit cards. The final page is for the backs should you desire. They are sized to fit into the standard sleeves for collectible card games like Magic, etc. which probably makes them a tad wide for UK A4. You should be able to choose the 'Fit to Page' and 'Center' option on any printer, manual load the pages and repeat the process for the backs and they will still line up perfectly. If you really want to go to town with these, print them on the heaviest card stock your printer will feed through and then laminate the pages BEFORE cutting out the cards (but AFTER filling them in with your units) instead of sticking them into sleeves.
Here is a sample card filled in...
These are based on the cards I made for my games...
I didn't post the fancy backs above because a full page of these eats printer ink, but I can add them if anyone really wants them. After cutting and laminating I used a specialty cutter I picked up from a craft store in the scrapbook section to round the corners and give them that professional finished card look.
Anyway, I hope you find these helpful. Let me know if I missed the boat and need to go back to the drawing board...
