Ukraine's army keeps outsmarting Russia on the battlefield, with cunning ruses and opportunistic attacks

• Russia has proven vulnerable to deception during the Ukraine war. 
• Ukraine has used decoys, cellphone data, and a range of other ploys to ensnare Russian troops. 
• Problems with Russia's command structure and equipment leave it vulnerable to deception. 

Deception has been at the heart of some of history's most successful military campaigns, and it's an art Ukraine has excelled at in its battle to resist and drive out Russian forces.

In many ways, it's had to. At the outset of the full-scale invasion, Russia's vastly larger army and equipment reserves appeared ready to quash any resistance.
