CQB (Close Quarter Battle)
Combat at short range, typically inside buildings, vehicles or other confined spaces — measured in metres rather than tens of metres.
Close Quarter Battle is the body of small-unit tactics and individual skills used to fight at short range, typically inside structures or in restricted terrain where engagement ranges are measured in single-digit metres. The defining features are speed, surprise, controlled violence of action and a level of section-coordination that compounds only with repetition.
For the Indian Army, CQB has been an active operational requirement across multiple theatres for decades — counter-insurgency operations in J&K and the Northeast, urban operations along the LoC, the Poonch and Rajouri ambush patterns since 2023, and counter-terror response in built-up areas. The doctrine is developed; the training tempo to keep it sharp at battalion scale is the limiting factor.
Synthetic CQB training is one of the most direct cases for VR-based military training. The terrain can be authored to match the specific compound or building type a unit will deploy against; the section drills can be rehearsed at higher frequency than live mock-houses allow; and the muscle memory transfers, provided the hardware (weapon-mounted inertial trackers, room-scale tracking, accurate weight) is right. SHAURYA-SIM is built against this requirement.
