I copied the green and white color scheme for this regiment from a unit of Bretonnian men at arms featured in a Rogue Trader era issue of White Dwarf. (Around #140, I think) Alas, once I had painted everybody's shirt and trousers in some combination of green and white, I came to the conclusion that the color scheme I had chosen was actually, unfortunately, really kind of boring.
The Halberdiers can't use thier shields in close combat, but they can be of use in protecting the troops from missile fire as they advance upon the enemy...so I have a lot of the boys with their shields slung on their backs, or shifting off their fore-arms onto their shoulders, as if they are closing with the enemy...
"Come on, Boys! This is what the Baron pays us for!"
"Give 'em the Baron's steel!"
