A joint military drill between Israel and the U.S. will begin tomorrow. 

IDF said that the exercise, also known as AC12, is the largest air defense exercise ever to be conducted between the two armies. These exercises are part of a routine training program designed to improve interoperability between the air defense systems of the two armies. Plans for the joint drill were begun over two years ago, and the exercise is not intended as a response to any specific events in the region.

"The IDF sees this exercise as an opportunity to learn and institutionalize cooperation between the armies. During the exercise, U.S. forces will be spread out throughout the country, near civilian areas... a number of roads will be closed for short periods to ensure the safety of civilian vehicles. At the end of the exercise, U.S. Army soldiers return to their country," said IDF spokesmen.
