Looting, suggestions? Options

[Damatory]

So my group played a pre-made mission last week and went rather well. We have a basic idea of how the mechanics work now. One thing I noticed in the pre-made is that every person we encountered had specific gear on them, predetermined in the mission plan.

Last night we started our GM's campaign/storyline, and I realized we just eliminated the opposition and drove on without checking their bodies. Mind you, it was pretty linear that way, we had to keep moving. Though I still wonder what could have been cherry picked from them.

My question is basically, what sort of gear or items would be common place to find on a random henchman? Obviously they would have a weapon, because they shot at us, but what else could be found?

Also, as an added bonus, would it be common to award characters with a higher loot from baddies for completing a particularly difficult part of the story, like a "boss fight" or climatic play session end?
