Could you give me a source for this?

Preferably a Finnish one. Not by language (although am Finnish so not an issue) but like a reliable source in Finland documenting that’s what they’re for?

I know we do have lots of infra designed “in case of Russian attack”, mainly the direction of roads on the eastern border, but I’d like to read up on this blowing bridges shit.

I mean its also very much usable for other stuff like hanging up temporary cables and hoses and in practice its probably used for things like that more often.

I genuinely just think it’s the construction crew just bending the rebar that they had as extra when building it, instead of spending time cutting these off to make it look nice.

As in they needed like x meters of rebar so they used x +0.5m to make sure there is enough, and in the end just couldn’t be arsed to cutt off the extra, sand it down, paint over it, etc.

Exposed rebar is a big nono in construction. It lets water in which causes rusting and eventually chunks of concrete start falling off.

I should’ve thought so as well but unless you can come up with better reasoning or source for these being for bombs, I still find it more probable. I’m not saying it’s a good explanation, but it’s more probable to me.

Anything I would was discussing “charge pits” and I can’t imagine any explosive you’d want to hang on the outside of what you’re demolishing with that sort of frequency.

I’m not saying it’s not true, but I’m not convinced.

As a pioneer I’m quite certain that the explosive you’re supposed to hang from there is just a plain anti-tank mine or few. It’s basically just a 9kg chunk of TNT - even has a handle.
