Surya Kiran is an annual bilateral joint military exercise conducted between the armies of India and Nepal [1]. The exercise is designed to enhance interoperability and strategic coordination between the two neighboring nations, focusing on counter-terrorism operations, jungle warfare, and disaster management in mountainous terrain. The 19th edition of this exercise was held in Pithoragarh, Uttarakhand, from November 25 to December 8, 2025, involving 334 personnel from each side. Historically, the Indian Army is often represented by the Assam Regiment or Gorkha Rifles, while the Nepalese contingent includes units like the Devi Dutta Regiment. These exercises reflect the deep-rooted historical and military ties between India and Nepal, often rehearsing sub-conventional operations under the United Nations Charter framework.
