The Russians in Kursk used two of their BTR-D armored personnel carriers as a base for a pedestrian crossing across a river. They placed wooden pallets on the armored vehicles, creating a strange structure that drew ridicule on social media.
This decision seems very questionable from the point of view of expediency, since the Russian army is experiencing a shortage of equipment. If the vehicles were faulty, dismantling them for spare parts would be a much better solution than flooding them in the river.
It is possible that both BTR-Ds got stuck in the river, and the Russians, instead of saving the vehicles, built an improvised crossing from them.
