I feel my character will have more of a importance if we go with boarding, because in ship battles you can just transport random people to the stations medbay and have the more experienced people help him

But on a attack the Medical Soldier will be rushed, probably face assault from enemies, and have less supplies than a actual medbay and it will have a more Saving Private Ryan-esc feel were Medics do absolutely nothing besides /attempt/ to help people survive and fail constantly.

Also it will add SPACE DEPRESSION
