Capture attempts are great.
They precipitate fights.
One lone guy turning hangers into smoking craters, simply for the sake of it, is toolshedding.
Bombing hangers in the process of capping a field for capture serves a purpose.
When the town is untouched, and troops are not even remotely on the way, it's toolshedding.
Toolshedding = bombing the highly dangerous, inanimate buildings that, in and of themselves, cannot do any damage to you.
Toolshedding hangers whilst both sides are trying to, and have been, furballing for a while is just pissing on someone's Cheerios and proves that the person doing the bombing has no skills or interest in flying fighter planes.
