William,

The ATGM Stryker is based on a TOW ITAS system. The TOW is very different from the fire control system tank soldiers are familiar with. You cannot fire TOW on the move. Once you launch a TOW, you must track all the way to the target. With the MGS and it's tank FCS, you can fire on the move over rough terrain. Also, tank fire control systems are like bowling. Once you fire, you can lean all you want, but the round is going where you aimed. There is no need to stay exposed when you fire. Once the gun goes bang, you can displace. The FCS also means that the MGS identify and track targets while moving.
