A cache with some military info as well.
Take you time and look at the Howitzer here on public display. Also read the list of those from this area who served in Desert Storm and Desert Shield. This is placed with permission do not worry about being discrete. You do not have to crawl or climb on the equipment. The hint may be a spoiler so use it only if you wish to make it much easier.
I would hunt this cache during daylight hours.
