I have not worked as an EMT for BCT yet (nor will I for the beginning of BCT), so I have not seen it in cadets. Saw it at a football game last year with a woman in the stands.
I work intramurals now, so I mainly see shin gashes from soccer, twisted ankles, and then I've dealt with several people in the dorms around me getting so sick they hyperventilate or start fainting. I just stabilize them and take them to the hospital. However, some of my off days people have had broken legs, twice from soccer. lol.
I expect to see a lot of little stuff and some bigger stuff in BCT.
