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.
Thanks for that and this is basically the reasons I guessed. This to my mind points out one of the problems with trying to flow the Stryker concept across a Formation. The M151 RWS on the ICV can be modified to take Javelin ATGM, so why have the TOW ITAS in the formation?

The calibre and FCS configuration on MGS strongly suggests an ANTI-Tank requirement. - that could be handled by a modified ICV.

The need for close fire support / HE Projection, is, IMO, not best served by a 105mm gun, unless the Anti-tanks requirement is what is driving the requirement.
