Mhh, I didnt notice any difference on the Jaeger jackets....
Well, the Cavalry Troopers (the guys with the jackets

.....), are just plain Jaegers with epaulettes and belts from the green Park Ranger, or bandoliers.
The other guy is an Infantryman, whose body is plain khaki (I think he´s from one of the older western sets) his belt is from the new Dirct Service Pirates (no partnumber available yet, sorry)
New khaki trousers and brown riding boots can be found at the horse cleaning set, btw.....
