To expand on this a little:>Germans
German equipment superiority manifests itself in a few ways. Firstly, their infantry tend to have more MG/Rifle teams or straight MG teams, giving their infantry a firepower edge against many other nations whose troops are predominantly Rifle or Rifle/MG teams. Germany also gets the gold standard of AT guns, the pak 40, and the gold standard of "medium" tanks in the Panther.
However, this equipment combined with german special rules and training makes them very expensive. As a result, german heavy tank lists are simply outnumbered and out-gunned by a wide margin. Also, german conventional artillery is generally seen as overpriced and unnecessary. Most german lists use light rocket launchers and mortars for smoke, and sometimes heavy mortars for digging out entrenched infantry. For similar reasons, german air support is also a rarity.
By the latewar era, the cheaper german medium armor, the stug and panzer4, are greatly outclassed by the russian t34/85 and the newer shermans. Panthers do terrible things to enemy armor, but cost twice as much as a panzer4 or stug with equal training, making your list even more outnumbered. The veteran german armor lists rely on their Stromtrooper rule to let their tanks shoot and move back into cover to make up for their inferior armor and guns. The tiger and king tiger tend to struggle to pull their weight in comparison to the panther.
German infantry in half-tracks have the (almost) unique ability to assault other infantry without dismounting, and can keep their halftracks on the table after dismounting to use as mobile screens and extra machine guns. Halftracks, of course, are very vulnerable to anything above small arms, which are often attached at the platoon level for everyone but the Russians.
