I have been playing on the 500pt at the start of the war June 41. I have found that this gives you a good mix. The size is a bit bigger than a couple of platoons or a single company...however I have found it the best to learn the combined arms that you will need later on. 2 Infantry units pounding on each other does offer a challenge but add some armor,support or other vehicle and it changes the tactics incredibly. Just my 2 cents.
