Theatre Level Operational Readiness Exercise (TROPEX) is an inter-service military exercise involving the participation of the Indian Army, Air Force, Navy and the Coast Guard. The exercise generally commences at the beginning of each year and lasts a month. It is generally carried out in three phrases: independent workup phase, joint workup phase and tactical phase.
The exercise is designed to test the combat readiness of the Indian naval units, as well as the Indian Air Force, Indian Army and the Indian Coast Guard.[1] It also seeks to strengthen interoperability and joint operations in a complex environment.[1]
Beginning in 2005, the exercise has been held annually, with the exception of 2016 and 2018. The last edition of the exercise was conducted in 2021.
