This is the infantry element of Pulaski's Legion (the mounted troops being here). In the "British Grenadier!" scenarios it appears as a unit of 6 skirmishers at Savannah. So far as I can tell, the only way to model this unit in 25mm without doing your own conversion work is to use KMM figures as they provide heads specifically for the Legion (KMM-08). This then gives you a choice for modelling the Legion infantry - you can use the generic Continental infantry figures or the newer dismounted dragoons. I chose the latter as KMM's proprietor, Bill Nevins, had sent me several packs of these figures and I was keen to try them out. The Continental infantry figures are probably more appropriate for the specific Legion infantry (as opposed to Legion cavalry who have dismounted to skirmish), but given that only 6 figures are required I don't really think it matters. But if you want to make up a unit of Pulaski's Legion infantry, then the figures in overalls and packs would be perfect.
I have 7 figures here because I wanted to add the officer as well (there's also an eigth figure in the range which isn't present in the unit - a standing loading figure). The rank and file figures are based in threes as second-grade skirmishers under the "British Grenadier!" rules. I suppose I could add three more figures and use this unit as the dismounted version of the cavalry, given that charging the fortifications at Savannah isn't really something any sane gamer is going to try (historically that didn't work out well for Pulaski). Like the mounted troops, I painted these figures about a year ago. I did take photos at the time but I wasn't really satisfied with them and decided to wait until the rest of the Legion was finished before having another go. To the right is a picture of the entire Legion, with Pulaski at its head. As I've said, these troops only feature in the Savannah scenario (although the Legion, or parts thereof, were engaged in skirmishes at other times), which is the orbat I have half an eye on at the moment. I'm currently working on more cavalry for both sides and I've also just added a couple of figures to my 3rd Continental Dragoons, to bring them up to strength for the Indian Field scenario - you can see those here.
