I'd say they're just hanging around and doing a kind of checkpoint-type thing, to keep an eye on anyone making it to the 'base' at the farmhouse, which is of course the primary recon objective.
I figure the plan for the unit from here is for Silver's group to eliminate the convoy to cause a ruckus, while the trio at the bridge get wiped by the recon team, and then they advance to the objective, with the assault group sweeping up to cover their fall back to cover after performing the recon.
I'll make a post shortly getting the shooting started, so we can actually get into something a bit more exciting than dithering about and procrastinating.
Winter, feel free to make a sheet and put it 'on hold' if anyone decides to drop out. I'll keep an eye on who's posted or not and let you know as soon as anything develops.
