I've decided to do all of the marines with yellow helmets. I will use the black shoulder to do the squad number and type identification. So this guy is a Tactical Marine - red - and he's from the 1st Squad - 1 stripe. Squad 2 will have 2 stripes. Go figure.
I also have updates on "Not Corbulo" but I haven't had time to get decent photos. Even this guy looks seriously washed out thanks to a quick photo under the sun. Ah well. One of these days I'll take photos I'm happy with -- until then I'll have to be content knowing the model looks better than the photo does.
