Is there a way to update civilian position in the RP profile? I might be going blind in my old age, but I don't see a way?

Under "Civilian Experiences", you should see two things that may be useful:

1) Use the "+ Add Experience" link to add a new civilian position to your profile.
2) Use the "Edit" link next to your current position to make an adjustment to a civilian position that is already on your profile.

Update: Thanks for the responses LTC Kevin B. and Capt (Join to see). The site was smarter than first cup of coffee me. With your help, I found the edit/update feature.

Not sure if your are a phone or computer. On my laptop there is an edit function shown with every civilian position.
