I’ve got a couple ex-military buddies that spew similar BS, and worse.
I just tell to em stick a sock in it because nobody cares what a washed-up potato-peeler thinks. lol
I had a twenty-some year Army vet throwing lead at a trail I was walking on. Flanked him, and he was teaching his boys to shoot... by shooting at water. I told him he should ‘t be shooting in that direction, and he said “Why not? What’s down there?” Genius.
