As the others say, the two ranges are quite compatible, and can be mixed together in units. Some of the Redoubt marching poses are excellent, they get the right shoulder shift pose spot on. Their "Band of Brothers" set is a real beauty as are the VMI cadets. My only gripe with the Redoubt range are the horses which are not as good as Foundry or Perry. In fact the best Civil War horses around at the moment for my money are the Perry plastic ones. All my metal cavalry are mounted on them, even the Redoubt ones, with a bit of leg widening.
