The main defensive line is made up of three parallel defensive belts, with a total depth of 6 to 15 kilometers, supported by minefields as deep as 400 meters. Antitank ditches are quoted to be 3.6 meters deep and 2.5 meters wide. These obstacles are probably 1,000 meters in front of the armored revetments (see Figure 3). Iraqi armor, mostly T-55s, is likely to form pack fronts, i.e., concentrated antitank fires being directed by one commander against one target. Earthen berms along newly constructed roads and tracks should allow Iraqi tanks to move where the action is and fight from protected positions. Over 500 miles of new roads have reportedly been constructed for this purpose. Battalion strongpoints are likely, allowing the defenders to fire into the Hanks of breaching parties. Between these strongpoints will probably be "fire sacks," based on the Soviet model, where massed indirect fires are concentrated. All of these defensive arrangements are designed to grind down the attacker, allowing the tactical reserve to seal the breach. - See more at: https://www.mca-marines.org/gazette/iraqs-defense-kuwait-and-battle-kursk#sthash.0SWoEWBb.dpuf
