In case anyone finds it useful, I've done a flowchart 'checklist' for combat in Road to Armageddon, and done my own version of the character sheet (since I was forever writing things in the margin or on the reverse of the official one).
Combat flow chart is here: https://drive.google.com/file/d/0B4PygceCez5WMVl4UkZWY2V1N3M/view?usp=sharing

It's cropped off the margins when I exported the files, so you'll have to add them back in again if you want to print these (unless your printer really likes printing right up to the edge of the paper).
My brother has requested an action dice/recoil/ammo tracker sheet to go with these. When I have time to do that I'll share that link too.
