The word "aggressive" is getting the wrong connotation in the fire service. Being an "aggressive" firefighter or an "aggressive" fire company HAS NOTHING TO DO with rushing in carelessly, cowboy antics and operating with reckless abandon. An "aggressive" firefighter or fire company's foundation is formed thru personal and company level training and a marked state of combat readiness!
Check out Merriam-Websters dictionary, 1b. insert "fire" in the sentence.
NO FIREFIGHTER IS INVINCIBLE, NO FIREFIGHTER IS BETTER THAN THIER TRAINING AND THIER EQUIPMENT PREPARES THEM TO BE! BE COMBAT READY, BE A LEARNER!
