Just a quick note. RW/WLF has been updated, from version 2.2 to version 2.4. This update covers oil slicks and road debris, and as well as adding the one shot heavy rocket to the arsenal. There are also some rules for limiting the game based on ammunition expenditure and a point-based victory point system (the last two optional appendices).
Anyway, you can find it in the standard places, under DIGITAL RULES on the DIGITAL RULES page. See that handy tab at the top of this page.
