<h1>Army chief: Theaterisation inevitable for unified command; jointness, coordination across services and agencies essential; GST cuts boost defence modernization.</h1> The Army chief said theaterisation - integrating Army, Air Force and Navy capabilities under unified command - is inevitable though its timing will depend on steps to achieve jointness and integration, noting coordination needs across military, paramilitary, space, cyber and civilian agencies. He acknowledged recent divergent views among service chiefs and the Chief of Defence Staff but said unity of command is essential. He welcomed recent GST cuts on defence equipment, saying reduced rates (notably for heavy equipment and UAVs) will boost defence corridors, MSMEs, R&D, training and modernization. On the Line of Control he warned state-sponsored terrorism and infiltration remain concerns.
