Resicast don't have any SEA troops at the moment. Firestorm as you mentioned and a couple of Warrior figures. You could adapt a couple of the Sovereign shirt sleeve figs if it's resin you want, but other than that there aren't many around.
I suggested the DML set as there are several sets of long trousers included.

I'm working om a small jungle scene too. Sorry I forgot about the Wee Friends chap. Figures I used were the two from Firestorm, the Wee Friends chap and a kneeling guy from Sovereign.
