What happened to face paint?

I think it stopped when the Army went to a uniform that didn't blend into anything any more. What's the point of concealing a face when nothing else blends in to the environment?

The problem with camo is that like so much else in the Army it was a "If it's good for one, it's good for all!" approach.  Depending on the terrain and WHAT you're doing, camo's a good idea.  But we did stupid things like making Abrams crews camo up, because that face under the hatch might give away the umpteen ton tank with the turbine engines.  Very simply, the determination to camo up should be an operational decision made by squad leaders and platoon sergeants.  Instead it became a decision of uniformity by field grade officers and the type of sergeants major who're more concerned with parades than practicality.  And baby oil is for neophytes.  Those in the know use green-bottle DEET in its banned carcinogenic oily concentration, usually found behind the counter of less than reputable surplus stores.  That stuff will melt a camo stick regardless of temperature.  Just don't get any around your lips or your mouth goes numb.
