Israel's military has conducted a multi-service exercise to test its capability to launch an invasion of the Gaza Strip. The military's Southern Command launched the exercise on Tuesday that included representatives of the army, navy and air force. Military sources said the exercise focused on the ability of the three services to communicate with each other and share situational awareness. "This does not mean we're invading Gaza," a military source said. "That's a political decision. Our job is to be ready for anything."The exercise consisted largely of simulation of scenarios in a test of command and control capabilities. The sources said the military has sought to ensure that army, air force and navy units assigned to the invasion would be interoperable.
