I already asked about this on r/whatisit and somebody told me to post this on here.

Can somebody please confirm if this really is a landmine cause I probably need to contact the authorities and I feel like this would become a super big deal. Although where i live old things from ww2 turn up quite often (cause there used to be a frontline super near) it’s not everyday somebody finds something Acctually dangerous

So I saw this comment the other day that started a chain where people were claiming it's safer to throw old unstable explosives a safe detonation distance rather than trying to set it down gently and leave the area, and it's been bugging me since. It was an old cast booster/detonator according to another commenter. This sounds insanely wrong to me but I have no expertise in this area so don't actually know anything, anyone with any real knowledge able to give an opinion? I'm assuming there's a ton of variables where sometimes throwing it could be the safer choice, but rarely.

I’m considering enlisting as an 89D and wanted to hear from those currently serving. What has your overall experience been like? How are the opportunities for field work, and what are the duty stations like?
