First of all, it’s the XM2001. The resupply vehicle is called the XM2002. There’s no XM2000.
I spent some time researching the Crusader in preparation for a suggestion, but gave up because I couldn’t find specifications for the magnification of its direct fire sights. In fact I have found no evidence that it was capable of direct fire (unlike PzH 2000 et al.), nor any suggestions that it had LRF or, as you claim, a full stabilizer (the last I find exceedingly implausible; AFAIK no SPHs were ever meant to have a stabilizer). Sources would be appreciated.
Anyway, some more info dump. Sources aren’t particularly reliable, but its the best we’ve got:
