The trainer in Norfolk had us wear coveralls when I went through it during "baby" SWOS.
Speaking of trainer, Norfolk built a new trainer recently. It's pretty decent inside, this time around though they made restrictions on water depth so that it wouldn't go above 3 feet. Weak sauce.
Yeah, weak sauce like going from diesel-wood fire fighting training to propane. The propane trainers are just fine, but I'll never forget walking into a raging diesel-wood trianer for the first time!
