Frog, I know you have been here for a long time, so Im going to tell you this as a friend.
I am a full time Guard guy (AGR). Im also qualified as a MP. Im also a supply sergeant, so Im going to go on a limb here and say Im a subject matter expert. Im high enough in the food chain to know everyone and not high enough to carry any real decision making clout.
1) Guard units do not just send equipment all willy nilly across the states by train. If you see GUARD unit vehicles loaded on trains, they are usually headed to Ft Polk or Ft Irwin for training exercises.
2) Those 3x3x5 rubberized bags are smoke launchers, and they are usually installed on MP vehicles. The rubber bags are covers to keep out dirt and rain.
3) There has been no 'secret' mounting of equipment. Trust me. It takes WEEKS of paperwork and red tape to move ANYTHING thru our maintenance system.
4) The National Guard, at least here in NY, has NO super secret microwave brain frying equipment. I wish we did, because Im getting sent into the thick of this nonsense this week. Most of us will just be 'brick targets' while the State Police lob the tear gas.
I really hope your post was in jest and someone says 'Scott, he was just kidding, relax'......
Be safe out there @ScottD hopefully this will pass before you ever see your first brick.
Totally serious. Be safe and godspeed.
