Ray - Thanks for the uniform regulations. Gatetraveller - thanks for posting the picture. iIt looks like the US army copied the British patrol jacket (or whoever's jacket the British copied it from in the first place).
So far I have figures either completed ot in the 'to be painted' box to produce the following:
2 x 10- man units (officer + 9 riflemen)
Colt MG with 4 crew
Driggs-Schroeder 1 pounder gun on landing carriage with 4 crew
Various officers and personalities (including a signals team)
Now I need to think about some appropriate steamtech for them. Thoughts so far for addition element for my force:
Impervious suits with gatlings or flamethrowers - these are on the 'must buy' list, but I haven't yet decided which manufacturer's suits I will go for.
An amphibious steam tank or troop transport - if I can find a suitable vehicle to base this on.
Some form of aerial gunship.
More marines.
Any ideas welcome
