The Israeli Army is launching its largest drill in neraly20 years, simulating a war with Lebanon's Hezbollah movement, Haaretz reported.

Tens of thousands of soldiers are expected to take part in the massive exercise.

The ‘Light of the Grain’ drill will last 11 days and will simulate “scenarios we'll be facing in the next confrontation with Hezbollah.”

It will include a scenario of instant escalation, in which the army has to defend Israel against multiple terrorist infiltrations in the north.
