First mission - being spotted while disguised.

[PoweredBySoy]

Hi, friends.

I just picked up this game via Steam yesterday. So far I love the concept and the gameplay, but I'm having trouble with a few quirks and how the game "expects" me to play.

So on the first mission, I successfully reached the enemy bunker and acquired the drivers uniform. Up until this point nobody has been alerted of my presence. I get into the truck and start driving towards the enemy base, but there are still certain officers that are able to identify me and begin shooting on sight. The most annoying one is the group that patrols the small canyon road - as there's really no way to drive by him without him seeing me.

Is there something else I should be doing to better disguise myself? I should note that while I'm wearing the drivers uniform, I am not wearing anything else like a backpack or sniper rifle that would give me away.

Thanks.
