First of the just like to say Resistance definitely rocks and is a welcome addition to the OFP universe.
But the main point for me is after reading about how you have to keep your weapons/ammo/men for the next mission on all the previews and notes around I decided to stock pile the Ural at the start of the game near your house for a good 20 minutes with everything I could find around that would fit in it, and how long did I get to keep that vehicle for. One more mission. Oh well.
It seems you can only keep your stuff when the campaign decides you can which could get a bit annoying.
