With reference to India's defence, consider the following helicopters: 1. Cheetah 2. Chetak 3. Rudra Which of the above has/have turret gun, rocket system and air-to-air missile?

The HAL Rudra is the Weapon Systems Integrated (WSI) Mk-IV version of the Advanced Light Helicopter (ALH) Dhruv. It is specifically designed for combat roles and is equipped with a 20 mm turret gun, 70 mm rocket pods, and MBDA Mistral air-to-air missiles. In contrast, the Chetak and Cheetah are primarily light utility helicopters used for observation, surveillance, and logistics. While armed variants like the 'Lancer' (a modified Cheetah) and an anti-tank version of the Chetak exist, they typically carry machine guns or anti-tank missiles rather than the full integrated suite of a turret gun, rockets, and air-to-air missiles found on the Rudra. The Rudra's armament also includes the capability to carry Helina anti-tank guided missiles. Therefore, only the Rudra meets all the specified criteria.
