The problem is, as I understand it (and I may be wrong), the MVP doesn't load skins automatically based on the date.
Anyway, when it comes down to it, it's just a different way of doing things, and if we'd known about the feature you're talking about we may have done things a bit differently, but I think SH3 Commander gives players just as much flexibility as the MVP mod, and it does it just as efficiently. In fact I believe SH3 Commander features more skins, because it has some extra late war skins added (although I guess if Iambecomelife has updated his mod recently, he may now have the same or more).
But whatever the facts are, if you like the MVP mod more than the SH3 Commander version, use it.
