The correct chronological order of the military operations is Operation Riddle (1965), Operation Cactus Lily (1971), Operation Meghdoot (1984), and Operation Safed Sagar (1999). Operation Riddle was India's response to Pakistan's Operation Gibraltar during the 1965 Indo-Pak War [1]. Operation Cactus Lily was an air assault and military maneuver conducted in December 1971 during the Bangladesh Liberation War to reach Dhaka [1]. Operation Meghdoot was launched on April 13, 1984, to secure the strategic heights of the Siachen Glacier, preempting Pakistani occupation [3]. Finally, Operation Safed Sagar was the codename for the Indian Air Force's role during the 1999 Kargil conflict, providing air support to ground troops to reclaim occupied territories [2]. This sequence (2-1-3-4) accurately reflects the historical timeline of India's major military engagements with Pakistan.
