A previous reviewer finds "it reductive when the characters address their seniority as "Boss"." I'm not quite sure what "reductive" means in the slightly odd context of this sentence, but I do know that any team has its own dynamic. The leader of the team can be addressed as "Bob" or "Ma'am" or "Bud" or "Sir" or "Captain" or "Marge" or "Chief" or "Boss" or "Fred" or anything else. The form of address doesn't matter: what does matter is the respect in which the team leader is held, and if they (the team) are comfortable with that mode of address. I have never been engaged in an active firefight, but my expectation is that the modes of address used between colleagues on such occasions are not likely to be related to seniority, more to survival. It took the eighteenth and nineteenth centuries for governments to wake up to the fact that enabling the enemy to identify officers was a BAD IDEA (plumed hats, etc). They've sort of caught on now. So now, to address an officer in the auditory presence of the enemy in such a way as to expose them as an officer may well be a capital offence. I suppose I really don't understand what the previous reviewer was getting at! But from years of managing teams, my bottom line is that it doesn't matter what the team leader is called, and they don't have to be called the same thing by each team member - it just has to be reciprocally comfortable for each member involved.
