No vegetarian tables at mandatory meals-but we also don't have ramps anymore, so there's less of a need for them. If you're a vegetarian, you'll just use your handy dandy vegetarian card to snag your entree at lunch or dinner. I don't totally remember how they work it during BCT, but I'm sure flight cadre are trained on how to accommodate.
Over the past few years there's been a big emphasis to prioritize nutrition and prevent weight loss as much as possible during BCT. Peanut butter is a favorite of basics, and if you lose too much weight, you'll get appropriate support from leadership.
