While the U.S. and Israel engage in air defense cooperation such as Austere Challenge 12, a drill meant to build soldarity, Iran’s current air defense exercise is intended as a “slap” to West.

Iran has modeled a new air defense system after the U.S. Hawk system, successfully testing the system in a move the country’s air defense chief on Tuesday called “a message and a strong slap to those countries that threaten [us],” the Associated Press reported.

Gen. Farzad Esmaili was referring to the U.S. and Israel, and constrasted those countries with others by saying the Iranian military exercise was “a message of peace and friendship to friendly countries.”

The Islamic Republic’s new system, “Mersad” (meaning “ambush”), can lock onto a flying object from 50 miles away and hit such an object from 28 miles out, according to Iranian state TV.
