There's no vehicles, and the teams are very distinct from each other: The basic US riflemen, for example, get the semi-auto Garand, while the Japanese are stuck with bolt action rifles. RS1 moves towards 'assymetrical warfare' a bit. Another difference is that RO2 includes tanks in some maps, usually one per team, though some maps have more, or only a tank for the attackers (there are tank-only maps but they're buggy to the point of being unplayable). The differences are NOT purely cosmetical (the German MGs, especially the MG42, are considered to be superior to the DPM, while the Soviet T34 tank is generally better than the German Panzer IV, for example), but still, the teams are mostly equivalent and can easily exchange defense/attack positions in a map, and they have the same assist choices (arty, scouts, etc, which the commander can call in). DPM vs M34 for MGs, PPSH vs MP40 for assault, etc). The German and Soviets have different gear, but otherwise their classes are pretty much shared, and each gun has an approximate equivalent in the opposing army (Mosin vs Mauser for the rifleman class, for example. There's some other differences besides setting, too (I'll skip RO1 since you're probably not getting that).
