I can't remember, I thought it was medic too?

You're right, it's only the medic armor.
"It is nearly identical to winterized combat armor, except that the armor is less beat up and dented, has different textured shoulder and shin plates, the medic symbol which appears on the armor's back and the missing balaclava and gloves. It has the same DR as well, but is less durable and gives a +10 bonus to medicine."
Still, it's
almost identical.
