and therefore technically speaking a "crew commander" should not be referred to as a "rank" but a job role, or position within the Fire Service.
Some firefighters dislike the use of the term "manager", as it implies an administrative role rather than a front line role.[importance?]
The new ranks to roles system has caused some confusion amongst firefighters on the fire ground, and from an administrative point of view at officer level.
If the officer in question is wearing rank markings on his / her uniform, other personnel can immediately determine his or her seniority.
This has caused great confusion between neighbouring brigades especially when not communicating in person because they may give their senior officers slightly different titles (they would wear identification marks on their uniform and therefore their seniority would be instantly quantifiable by officers from other brigades)
