The M2A2 ODS is a very nice build, better than I initially thought. They new pieces fit perfect, the old M2 kit is a good base and the new tracks are a nice touch.
The M113A2 is...not as good a buy. Old rubber band tracks are the worst culprit. Not sure this is worth the price tag. However, there are SOME updated parts, so it is not a total loss...just a dissapointment.
The figures come with the kits. They are fairly decent but they all have "pointy chins" because of the molded on microphones.
