Russian troops face captured tanks on battlefield.

A Russian sabotage unit claims to have drowned a German Leopard tank in a swamp in Ukraine's Kherson region. Videos on social media show Ukrainian armor getting bogged down in the seasonal wet ground, indicating Russia might exploit the geography to destroy more of them. The mud renders fields and unpaved roads impassable for around a month in the fall and spring. Russia seems to have repeated a trick from history in the current war in Ukraine, which is reaching its most decisive phase.
