I have heard several training excersises. It is also the only time I hear them mention any firemans names like Johnson or Smith, probably those dummies that they have drag around to simulate a real person, like the firefighter challenges on OLN ? On real calls you'll hear them being addressed by their title/rank; Captain, Chief. I was in Peel Region several weeks ago and heard the fire dept trying to rescue a fireman who fell through the floor and broke his leg and was running out of air. He was gasping for every breath due to heavy smoke as he was trying to give directions as to where he was in the building. He wasn't always answering his radio, long pauses between words, deep breaths, often no responses at all. It was very intense as I was driving in my car and listening to this unfold. Then, after some time, someone said "Remember to use proper english". That's when I figured out it was just an excersise. It sure as heck sounded like the real thing !!!
