Vladimir Putin’s forces have rehearsed using tactical nuclear weapons at an early stage of conflict with a major world power, according to leaked Russian military files that include training scenarios for an invasion by China.
The classified papers, seen by the Financial Times, describe a threshold for using tactical nuclear weapons that is lower than Russia has ever publicly admitted, according to experts who reviewed and verified the documents.
The cache consists of 29 secret Russian military files drawn up between 2008 and 2014, including scenarios for war-gaming and presentations for naval officers, which discuss operating principles for the use of nuclear weapons.
