Extremist militant groups have been depleted in the Sinai, they are no longer able to fund or arm themselves sufficiently due to the tunnel closures which is also limiting their movement. They no longer attack forces stationed there due to the Army's conventional superiority which lead them to this point.
Now they use improvised explosive devices to target convoys, that so far has failed because the military uses electronic warfare measures when it has forces on the move, so remote detonated devices don't work. The militants have taken to hiding within the population which unfortunately has resulted in collateral damage but the affects of that have not been harsh since it's a rare occurrence. The military is continuing its raids which on the whole are quite successful, the leader of the most prominent group in the Sinai was killed in one a few days ago.
What is dangerous though now is the movement of fighters from the Sinai to the Delta, this has already had an impact with the death of 3 troops being transported in Cairo and a few days back 6 troops manning a checkpoint, both of these times the forces were not armed or on duty, it's a dirty war. Today we lost another two soldiers in a raid on militants, the forces killed five of them and captured another four, one of them was a commander in the most prominent militant group and another is suspected to have been involved in the killing of the six troops at the checkpoint, either way the raid put a dent on their bomb making capability as it was a raid on a bomb manufacturing factory they set up. Egypt will prevail and sooner than people think.
