CaptO where does a PFC fit in
Well Rock, being a private first class is much better than being a private no class (E-1 or 2). At least there was a vote passed in congress to get you your PFC rocker!
In the Marines a PFC is an E-2. An E-3 is called a Lance Corporal (inherited from the British Royal Marines.) A PFC has one stripe and a Lance Corporal has one stripe above two crossed rifles. Getting you crossed rifles is a big deal because it shows you’re not the bootest of the boot. I'm sure you were probably interested mostly in the pay hike, yes? The mud was probably just as cold and wet in Italy as a PFC as it was a Private. Mauser bullets probably don't care much about the difference between E-2's and 3's as well.
I'd say PFC or no, you made an impression on people!
