The military never marches in parades with loaded weapons.
I don’t know if they’ve removed the bolt, but they aren’t going to shoot anything. But everything is a conspiracy these days.
Way back in 1972 I marched with the bolt in my M-14.
In 1973 they had us take the firing pins out. That took an armorer about 5 minutes per gun, and the rifle looked much the same, but couldn’t fire.
