A lot of text for someone who failed to address my point on unnecessary bloat. I never claimed that bicycles or motorcycles weren't used in wars or fought as battalions. My point was that they would be better served as simply evolutions or possibly variants depending on how the system works of cavalry battalions. The primary advantage of this is that you don't have to reform a huge chunk of your army if you want to stop using horses in the late 1940s as the US or USSR who has plenty of mechanized assets and no fuel problems.
Likewise there is no such thing as a superheavy TD nor a heavy TD. Simply changes and differences in the doctrines that nations used. The US used light, turreted TDs, Germany used light turretless TDs that eventually evolved into heavier vehicles. Claiming that TDs should be broken up as such is like claiming we should have super heavy, heavy, heavy-medium, medium, medium-light, and light tanks because the Tiger II was much heavier than the Tiger I and later Sherman variants used guns that were more effective against tanks. Honestly i would much prefer streamlining the division process, leaving it moddable so if someone wants 100 types of battalions they can mod in four different TD types, super heavy assault guns, and elite units for each nation. That way I don't have to sift through tons of battalion types that are redundant and that I will never use just so I can make a division with some mechanized infantry, some SPA, some engineers, and some armour. That is what 99% of this is going to be anyway, infantry, combat support, non-combat support, and armour.
I mean I want assault guns and light infantry, but I don't want arbitrary elite units like commandos that can be fielded in large numbers. Sure commando battalions existed, but only a handfu, not 90+ per nation.
