Ah Yes, this is one of those little bugs that pops up from time to time but the frequency of the reports is so few and far between I forget if we fixed it or not. If you ever see it again and you took a save just before it, try doing the exact same things again from the save and if you get the same added movement please zip it up , explain what we need to do and what unit's involved and post it here and we'll dig into it.

As Andy noted you can think about this as a really
REALLY inspiring speech from the NCO ( or he just rolled a grenade under the squad
) . For all we know the "bug"
may be in the rally code and you just rolled the electronic equivalent of boxcars--twice. But we won't know for sure until we can repeat it
