The Ukrainian Defense Department has published photos of new fortification structures they are erecting these days near Mariupol city. This city was widely rumoured to be the scene of the next major battle last year after Donetsk and Lughansk, but it turned out to be relatively peaceful except for one devastating shelling of the city suburbs and maybe a few other minor incidents. So they are building these structures – not from wood as might be seen here, but from metal boxes
So those are the metal boxes – bunkers dug into ground and covered with 1,5 meters of concrete and wood and as they say “can withstand the shelling from Russian weapons”.
Doors and windows can be locked with huge metal locks.
This is unique engineering made by the Ukrainian army and catering to today’s needs. For example, it’s hard to design these structures in parts of the world where there are no major conflicts, so they have built it with the experience they got in last two years and according to the needs of their army.
