If the government comes to your house saying they want to borrow your land for military exercises and that they will clean up the land afterward – run, run for your life. The military needs to be ready for the missions set before them. One way towards that goal is to practice using “live” ammunition. The problem with using things that go boom is sometimes they don’t. That is, the artillery or mortar shells sometimes don’t explode and instead embed themselves in the ground. Hence, when it comes time to clean up the land and return it to the owner, well, all I can say is don’t tread too heavily upon the land.
