Hi Terry - well that's a good question! My son was a bodysnatcher but I haven't heard specifically of a "railguard". Guess we'll rely on you to get more info from him regarding this! And please share when you do ;-D
Here's the link to the 900s Division group:
Maybe if you go through some of the old posts you'll find something on this. Or maybe Anti M will respond. She was in the Navy and is our "go to" for all things Navy lol!
Also, be sure to join the boot camp group - I left the link in the welcome message on your page and also your PIR group if you haven't already!
Taking a wild guest Here, but when I attended PIR they had Sailors directing the people as they went upstairs to sit. and they were posted in the front of stairs to either help or direct people also they were there to make sure nobody was standing.. That is my guess?
Phoenixmom - that is my best thought as well!!
