Now being just a nod and everything, damn near everybody is superior to me with the exception of maybe my boots. Only problem is, i'm having trouble figuring out how to address people, and having thought it through... asking a member of the training team about this, it may be taken as a "dumb" question. and I figured this is an easier way to get an answer and not having to bang out however many press ups for said dumb question. For Marines, i've gathered it's just Staff L/Cpl - Corpral Cpl - Corpral Sgt - Sergeant C/Sgt - Colours Sergeant and every officer as Sir. but I'm kinda confused with WO1s and WO2s.... what should they be called? I've only met one WO2 so far, and thankfully didnt have to make a (ock outta myself talking to him, but still. any light that could be shed on this would be appreciated.
