Yellow Cross Painted On Hood Nose. What does it mean?

[Stranger]

On certain surplus auction sites you will see some M939 series vehicles with yellow crosses or "plus signs" spray painted on the nose of the hood. Often they will have "OK" painted in the same yellow color on the side of the hood as well.

Anyone know what that means? Was it a military thing? Something the surplus agent painted on?

Something the surplus agent painted on and meaning varies from place to place. Ft Riley used to mark the headlights with yellow for awhile but stopped. Some places it meant "OK" it runs rebuild it other place "OK" too much wrong get rid of it.

I liked when they used , "DR". Does run, or don't run.

Contact the seller and ask...

[facepalm] Why didn't I think of that?

So, I called and asked the POC. He said the crosses were painted on to differentiate between trucks that had been released for auction and ones that hadn't been released for auction. It didn't matter in the end because the entire lot was released for auction.

He suspected the same for the "OK".

I have seen X but no cross. Also different color engineer tape on grills or bumpers. Someone's code but I have no clue...
