How did they get that up there - They Released It Into The Forest

There could be a whole heap of possible scenarios behind this story.... OK going only by what I see - I didn't see any fresh marks in the grass... rolling or tyres... and when it started rolling down the hill, it appeared to be out of round and flattened in on one side..... Maybe it has been dropped from a damaged aircraft a long time ago.... "Jun 20, 2019 Croatian soldiers defending Livno using a naval mine against Serb forces in 1992."

You are however free to dig deeper......

These things tend to be extremely well built, in terms of bobbing around in sea water for decades, highly reliable sealing, and components etc., and UNLESS it was professionally defused and the detonators removed...... I would not want to be anywhere near it. If one washed up on a beach, and it was remote enough to do it, perhaps gently placing a BIG 5 Kg plastic bag of explosive onto it, and sticking in a very accurate timed fuse of probably 20 minutes.... AND somewhere to hide behind / under cover... Re this rather ho hum video - https://www.youtube.com/watch?v=6_WKr-G6Lp8 There was a hospital in Australia with a lake in front of it.... and it was 2 Km away from the shore line on the other side of the lake.... (I got that wrong sort of) The I guess 10 storey hospital was being demolished with explosives to drop the center and it would all fall inwards. --------------- This footage captures the July 13, 1997 implosion of the Royal Canberra Hospital on Lake Burley Griffin. Explosives were detonated to demolish the hospital, but charges were incorrectly placed, resulting in steel and debris flying outward toward spectators across the lake YouTube ABC . What happened: The ACT Government promoted the implosion as a public spectacle, drawing around 100,000 people to nearby shores ABC Wikipedia . Tragically, a 12‑year‑old girl named Katie Bender was watching from Lennox Gardens—across the lake—when a steel fragment hurtled about 430 meters and struck her in the head, killing her instantly ABC courts.act.gov.au Wikipedia . The fragment, a triangular piece of mild carbon steel (~1 kg), traveled at about 128–130 m/s (roughly 460 km/h) and had enough force to decapitate her scalp and skullcap—the impact was described as akin to “a cricket bat being swung at 432 km per hour” courts.act.gov.au . Nine other people were injured, and fragments were found scattered hundreds of metres away Wikipedia ABC Region Canberra . Aftermath & investigations: Subsequent inquests revealed severe safety failures: lack of engineering oversight, inadequate protective measures, poor blasting methodology, and dangerously minimal exclusion zones courts.act.gov.au +1 . The coroner identified gross negligence by those responsible for the demolition plan and placement of explosives courts.act.gov.au Wikipedia . The tragedy remains a case study in public safety and the immense risks of treating demolition as a spectacle ABC Region Canberra . ---------------------- Yeah shrapnel can go a LONG way...... AND the mine is essentially a good thick tough steel shell, to resist rust, time and modest impacts during handling, it's not 3" thick.... it's just a shell - but big pieces coming edge on.... Ehhhhhhhh ---- don't want to know about it...

Unless that sea mine was professionally defused and the detonators removed - I would avoid it like the plague..... It's probably about a meter in diameter, with say 60% explosive fill for boyancy and other internal equipment for various functions.... and detonation etc.. (chatgpt fucks up so badly - off the top of my head this has probably 130Kg of explosive fill... That even iff wrong in amount - is a lot of explosive.....
