Not asking for any changes but are we able to rehearse the sentence about the frown / teeth so that it can be more clear? I know to us Sandtroopers we know what specific terms refers to but it might not be the case for new enlistees.
1. Frown: Can we use mouth or something suitable because although I know frown generally means the mouth expression in America but outside America, like where I am from, frown means the the eyebrows expression and some new troopers might think we are referring to the brow of the helmet.
2. Teeth. I think we should specify clearly what teeth means here. We can say teeth refer to the actual grey teeth and the gaps in between the teeth separately. Eg: 3 or 4 gaps on each side of the mouth for total of 6 or 8 gaps.
3. Frown is painted gray. Some people might confuse this as painting the entire frown, be it the mouth or the brow, grey. Like ROTJ. Which in fact should just refer to the teeth.
Just my humble 2 cents.
