Pros: That Army Slogan is No Slogan At All - It's Reality/ An Army of One!
Cons: People do get hurt and killed
As tank Commander the day is 24 hours. Training the crew/s -practicing and drilling safety and fighting skills. The tank is the most important asset of a tank command, quick changing tracks, repairing the engine and doing it under stress, under fire, and in hostile environments.
Learned how to be a leader of Men (women included in that term) of people. How to be firm, forceful and yet get them to respect and want to follow you into battle.
Management in the military is different from civilian management - there were great ones and some not so great. Let's leave it there.
Co-workers in the military have no choice but to get along if not body bags are cheap for the military industrial complex buyers.
Hardest part of the job was making the green and weak, strong of mind, body and soul and willing to pull the trigger.
Most enjoyable part besides sitting on top of that tank hands draped across that 50 cal machine gun, directing the men through desert sands or swamp waters, mud and rubble, was knowing after this they could protect themselves and the men and women following in their wake.
