If we get night back instead of this persistant daylight, we should get flares for gv's that might have carried them and fighters. If gv's didn't carry flares then hey, infantry probably did and what would be accompanying tanks...that's right, infintrymen.
The flares could be used to mark ground targets or friendlies at night, and fighter droped flares could be used to indicate targets for high alt bombers. We could get those star shells and that would create a better combat environment for gv's.
I know you probably have objections, but instead of focusing on the negativites, think about wether or not you would carry a few at night if some gv guys asked you to mark targets.
