You don't mess with the citizens of Kryvyi Rih.
The largest industrial city in Ukraine, and the hometown of President Volodymyr Zelenskyy is known for producing iron ore, steel and fearless leaders.
"Kryvyi Rih is the iron heart of our country and the people who live here have an iron character. It's impossible to break us," said Colonel Oleksandr Pyskun as he oversaw military training for around 100 local civilians.
