Full Form of LWM
What is LWM?
Light Weight Mortar (LWM) refers to a portable, man-portable indirect fire weapon system designed for infantry support. Typically having a caliber of 81mm or 120mm, LWMs are constructed using advanced alloys and composites to reduce weight while maintaining durability and accuracy. In the Indian context, the Indian Army has inducted modern LWMs (such as the 120mm LWM from Indian Ordnance Factories) to replace older, heavier models, enhancing tactical mobility especially in mountainous terrain like the Siachen Glacier and Kashmir Valley. These mortars are used by infantry battalions, special forces, and rapid reaction units for quick deployment in forward areas. The LWM provides high-angle fire capability, allowing troops to engage targets behind cover or in defilade. It is a critical component of India's artillery modernisation programme under the 'Make in India' initiative. For defence aspirants (NDA, CDS, AFCAT), understanding LWM is relevant in questions on infantry weapons, indigenisation, and modernisation of the forces. The system's role in recent conflicts and exercises (e.g., Exercise Yudh Abhyas) underscores its operational significance. LWMs are also exported to friendly nations, showcasing India's defence manufacturing capability.
