ISIS's improvised mechanized units in fight to hold Mosul

Washington Post:

These are the suicide cars and trucks that made the battle of Mosul so bloody

To carry out some of its deadliest attacks, the Islamic State weaponized everyday vehicles — from sedans to tractors — for use as precision-guided munitions.

In the end, the best they could do was prolong a losing battle.   The enemy has found the means to create objects that can kill a lot of people, but they are not enough to overcome a military operation against them.   The design looks like it may be somewhat effective against small arms fire but would be no match against modern armored vehicles.
