Actor Varun Dhawan will be seen in a completely fresh avatar in his next, Border 2. However, in order to do justice to playing the role inspired by the real-life war hero, Colonel Hoshiar Singh Dahiya, he had to undergo some intense training that included strength training, endurance work, and mobility.

Talking about his role, Varun revealed that even playing a soldier on screen required a certain level of physical and mental discipline.
