Most bridges here do, and often when one needs to be demolished and rebuilt, the military blows it up just for practice.
Edit: Source for the sceptics
The deep demolition, which became a central element in Finnish post-war demolition tactics, and especially the development of readiness to counter surprise attacks that emerged as a threat scenario in the 1960s, received significant support immediately after the wars. The decision concerning structural demolition preparations for bridges was made on January 15, 1946. These preparations meant building charge wells, charge chambers, charge pipes, and charge hooks. Authorities responsible for constructing bridges were required to include the aforementioned structures in their plans, which significantly improved the readiness to destroy the bridges.
If it was not possible to place the charge space inside the abutment or pier, charge hooks could be embedded in the supports during the casting phase, to which the charges could then be attached.
I don't have the energy to try to take this hill from someone who has watched too many movies or Hearts of Iron IV to even take this realistically, you get to live this day.
I'm a supply core undersergeant, so I literally went through lists of military equipment when I was serving. Never saw anything related to using antitank mines for improvisational demolition charges.
Just admit you don't have any reason. You can't rationalise it, but despite the overwhelming lack of evidence and logic, you still believe it. This is why Finland (or rather Finns) suck.
Blowing bridges isn't something you do when you're doing a tactical retreat. Blowing up bridges is something you do strategically. Guess you can't tell the difference, both synonyms to you?
You are deeply, deeply repulsive to try to chat with, I hope you have friends in real life.
Yeah I find it deeply annoying to talk to whiny people who get upset when you question something they've said. In fact I make it a practice not to be with such people, because they're usually really emotionally unstable. Usually it's the less intellectually robust people, and they get mad when you remind them of it.
See what you've just told me is you're repulsed by even the suggestion of "try to rationalise this thought you have".
Eww.
"Charge PITS."
But I'm sure that's just a translation error, right?
