Arjun (tank) equipment records. Variants, orders and quantities are shown as reported in each inventory source; coverage is incomplete.
Army exact named equipment holdings: Arjun. Active, operational-reserve and training units excluding equipment in store; November 2025 IISS assessment. Named service only; no parent-force or national total inferred. Source role: ARMOURED FIGHTING VEHICLES / MBT. Original estimates, ranges, reporting names, reserve, lease and employment scopes retained; nested included counts are not added. Missile-system quantities mean launchers, not rounds. No readiness, crew, carried weapon, payload, factory-production or future order count inherited.
Reported count for Arjun Mk 1 Arjun Mk 1A. Service scope: Indian Army; does not replace a national total. 1 distinct count cell(s) from the same source list; shared rowspan cells counted once. Excludes retired/reserve/on-order rows. Count column(s): quantity: 124 (Mk 1) 2 (Mk 1A). Origin: India. The listed variants/roles are the scope, not an immediately deployable count. The components do not establish one inventory census date; the stored date is the retrieved source snapshot.
