I think the difference between Cobra Officers and the standard Cobras is the number of hit points they have. Based on the cartoon though, I'd guess both have less than 4 hit points.
I'm still rubbish at painting the Cobra logo though. If you squint, you can maybe trick yourself into thinking it's a Cobra logo.
If only there was a little tiny Cobra stamp I could use instead...
(Only one of the original 16 figures left.)
