The new request includes: 400 M1126 Stryker Infantry Carrier Vehicles (ICVs), which replace the array of LAVs Iraq had been seeking. An accompanying request for 400 M2HB .50 cal Heavy Machine Guns would equip the Stryker ICVs with their standard defensive weapon, which is usually mounted in one of Kongsberg M151 Protector remote-controlled weapon turrets. Note that an order for those turrets would not require a US DSCA announcement, if it is placed with the Norwegian firm for manufacture in Norway.
Previous requests for LAV-25s are canceled, and the Strykers appear headed for Iraqi National Police, not Iraqi Army units.
