Strike 4 will be using a very modern version of a bomb. The SDB, Small Diameter Bomb, first fielded in 2006 is truly a weapon designed for the "current fight" or Counter Insurgency Operations (COIN). It is smaller than the defunct Mk81 at only 200lbs, but it has a range of 60nm and is very accurate.

You have 8x GBU-39/B SDBs and 6 small buildings to destroy. Use your munitions frugally to destroy all buildings.
