That's what I'm getting at though; it doesn't lower the stakes for the hero, and in some cases raises them.
Consider a classic superhero scene: police on a stakeout trying to figure out how to handle a hostage crisis. Superhero rushes into the building, solves the situation, and police try to arrest them for their vigilante work as they flee the scene. So why is that same premise suddenly off the board so often in DC comics when it involves larger scales of action? Batman comics do variants on this scene constantly. But seem loathe to do it when the entire city of Gotham is taken hostage. This seems very weird to me.
The military doesn't have to save the day to exist and its response to or failure to respond to the situation can make the hero's job that much more interesting and heroic. Marvel involves the civilian military on behalf of heroes, villains or on behalf of a third party as in the above classic scenario pretty frequently. Again, this doesn't make their stories any more realistic but it makes their world have a stronger sense of narrative. Cities feel less like cardboard backdrops. Marvel does plenty of other things to irritate me so this isn't a Marvel vs. DC thing as such, but there happens to be a clear imbalance between the two publishers for the sort of thing I was noting.
