How should someone handle a disrespectful PFC (as a SPC)?

Tell him to meet you after work, have a drink and kick his ass. That should solve that for a while.

With rank comes responsibilities. And one of those responsibilities is to teach subordinates respect. I'm sorry, disrespecting someone who outranks you is just asking for trouble. However if his squad leader or team leader won't do anything about it then go to your squad leader or team leader. You shouldn't have to put up with that kind of behavior. If all else fails catch him away from his leadership and smoke the hell out of him.

Had the same problem, early 80 Germany. we were very SPC4 heavy so we had them as TCs ect. Top would put senior SPC4s in charge of details. anyway PFC 1 giving me grief, PFC 2 telling him to can it.. just then Top came around the corner. problem solved.

Try your chain of command, you said different company right. Tell your squad leader, or platoon sergeant.

There is no excuse. I am outranked by kids almost half my age. It's a maturity thing and needs to be corrected.

Finesse or force, either sit down and have a couple of beers together or meet up and have it out. The bs has to stop.

Punch him in the face. Well that was an Old Army response sorry.

I don't care if you don't like the person but rank is rank! That disrespect PFC. can be brought up in charges!! It doesn't matter if his squad leader didn't like you!!! Rank is Rank!!! If he keeps it up, then go up your change of command! Itv

Put him in his/her place and let them know the UCMJ works both ways

We would just take him out back and if he slips and falls a few times then oh well. Probably not the right answer but it worked very well
