yes, that's the leather casquet/cap being worn by the French light infantry, which is great to see: just what you want for French in Egypt.
Between the different hat crests and the coat colours, you can paint an army with every unit in different colours (the 21st legere in sky blue coats with yellow, later pink facings and green and yellow hat crests!).
Again, nice lively poses, and i reckon they should paint up great. i especially like the officer, who looks very Revolutionary Wars with his mameluke hilted sabre. If i had a criticism (and i don't expect anyone's asking for one!), its that the coat tails are a little long on some of the figures: really the single-breasted coatee should barely cover the butt cheeks.
I do hope that Strelets are going to do fusiliers in this mode of dress, without the sabre briquet and epaulettes.
