I've seen a multimillion dollar exercise, involving thousands of troops and hundreds of vehicles and aircraft, come to a screeching halt because one of these things decided to go for a stroll.
And we could not move until the OC's had determined that was the only one on the move.
Considering what the Army has done for those things all those years...it’s a surprise this was not done sooner. The long haired hippies will, like the sonar decision...learn to “put some ice on it”
