After an impressive year-and-a-half of armed camping trips and extracurricular partying funded by the American taxpayer, I am an Infantry Platoon Leader (also, after a mercifully short stint in purgatory... er, staff).
As a new garrison PL, you'll see that if you suddenly evaporated tomorrow, your platoon would continue to function without any disruption (on account of the half-dozen NCOs who have been soldiering since before I hit puberty). However, I will do my best to influence my platoon in a positive way, so that, you know, my existence has a purpose. And, perhaps, one day my veneer of authority could develop into actual authority. But let's not get ahead of ourselves.
