As with all that is airsoft, you're the judge and gentleman.
I've seen teams with several medics, and medics without patches. Arbands may be stolen as souvenirs or lost. In the chaos of battle, a small goup of survivors may team up and fight on their own, if they by chance they are medics since they belong to other teams and for this one ocation fights as one small squad, should all but one remove their arbands? As a gamemaster i'd be unsure, but probably let is slide because of the situation.
The purpose of the cross is identification. not for snipers, but teammates.
I'd give a "dead" medic priority if i am healing people and so on.
A green band with a red cross usualy goes under the radar since it's mostly a "internal matter" for the team or platoon. And i've yet so se a gamemaster that cares. But if someone in the feild complains, we are forced to "suspend him as medic" and demand that he presets a correct arband before proceeding.
This applies to all improvised arbands, like for instance the huge medic patches in stead of arbands. If BE say people can use patches in stead of arbands someone will start to speculate in how small patches they can use before someone call theom out on cheating.
If you decie to bend the rules, know you are in theory cheating. So keep a propper arband on you if someone having a bad day and ruins your fun
