Just a thought while reading through the Real World 21st Century Ground Unit Templates thread.
To give a bit more variation between Light, Medium, Heavy, Super Heavy and Ultra Heavy weapon components, why not make it so that lighter versions have more shots?
So for example, Infantry Personal Weapons have 1 shot, but Light Personal Weapons have 2, or Crew-Served Anti Personnel (again, infantry) have 9 shots, and Heavy Crew-Served Anti-Personnel has 6 shots.
Just thought on weapon based components, since they're not as diverse in terms of differences in size except in AP and, well, Size.
Maybe rapid versions of those components that have more shots then normal, but less damage/AP?
