"Probably will show that platoon having more "action" in the first season (how long is a season again? 30ish episodes?)"
More like 13 episodes. But that's always been the case, private detectives don't get hit on the head every week and still function in real life, MDs don't get to trace the origin of mysterious & exotic diseases no one expects to find in Kansas, the roof doesn't collapse with every fire, etc.
