Yeah, you can use vaseline, pomade, or pull a pardus and smear bunkmate special sauce on your face like you're a burger with mayo... but here's the thing with that whole deal.
Are you as a troop with a beard, going to slather yourself with a trowel's worth of vaseline on your face, EVERY MORNING that you have an NBC defense posture above "don't worry about it"?
I call bullshit, and unfortunately if you fail to do that and encounter a NBC environment... congrats, you be dead and now your buddy to your left and right has to deal with watching you die, then more than likely you being a field burial since it's not like they're going to ship a slimed body home...
