Area used for training soldiers

How to tag an area which is

• Used to train solders
• Large-ish, several square kilometres, mostly forest and countryside (including cattle!)
• Not, strictly speaking, off-limits to the general public, but
• may be noisy and risky ("blank" ammunition firing, combat vehicles doing "tactical" driving, ...)

landuse=military, military=training_area looked promising, but, judging by the wiki, training_area is more of a research/test facility and not so much about squaddies doing the same ambush over and over again... And if call this a danger_area, what, then, do I use for the areas where there actually are live shells dropping out of the sky, and where you get prosecuted if you enter?
