Poll: Squad leader for a gun using healer squad

 I'm currently working on the draft for a future vanguard squad, which uses guns but can heal allies. 

After some back and forth, and cutting some of the ideas, I got it down to 5 options for the squad leader, and turned it into a poll to see which idea you like the most: https://strawpoll.com/polls/XmZRjK7NwZd
