I see a lot of posts breaking down infantry vs armor on a purely attack/defense power per IC basis. I'll agree that infantry has the edge in that sort of analysis but Armor has a huge manueverability advantage and also allows more concentration of power within your stacking limits. Once you have a breakthrough situation ARM/MOT/Mech are in a much better position to exploit that advantage than infantry are. Achieving that initial breakthrough doesn't really depend on force mix, it depends on local superiority regardless of unit type.
A mixed army will be better able to complete encirclements and thus destroy enemy units completely rather than allowing them to retreat. It will also be able to reach strategic objectives and chokepoints faster and more reliably. Obviously if your choice was to go either all INF or all ARM, INF is the clear winner but having a mix of forces provides a significant advantage. They key is figuring out how large of a mobile force and how many special forces like MTN/MAR/PAR you need to give you that edge and then fill the rest in with INF.
The obvious assumption is that both sides have enough INF to prevent the other side from steamrolling them with sheer numbers. This does NOT require equal numbers of INF to given the advantage that the defender gets. If the other side outnumbers you 10 to 1 it doesn't matter what you have, you're going to lose. A 2 to 1 disadvantage is quite manageable though especially if the underdog has superior doctrine, as Germany does initially.
