Looked in the manual but there is nothing regarding 'rearming'

[greyseal494]

so is this one of the planes where you have to be shut down, canopy open?

would be nice if DCS put this info somewhere

[Sarowa]

No, you can refuel and rearm with the f5's engines running and canopy closed.

If you're having issues requesting air supply connect/apply to start the engines while refueling or rearming, that's because the ground crew only does one thing at a time.

I can request rearming, I just don't get re-armed.

Can you post a track file? Or at least a video?

@greyseal494 Check that the base you're at is in the same coalition as your pilot. If the base is enemy or neutral, rearm/refuel/repair won't work.
