The teaser of Salman Khan's Battle of Galwan was released recently on the actor's birthday. While his fans were elated to catch a glimpse of him, the film has been criticised by the Chinese media. The film draws from a chapter of India's Most Fearless 3 by Shiv Aroor and Rahul Singh, a bestselling book chronicling extraordinary stories of courage within the Indian armed forces. It is based on the real-life confrontation between Indian and Chinese soldiers along the Line of Actual Control resulted in the martyrdom of 20 Indian soldiers and significant casualties on the Chinese side.
