Glaive confusion

[Adept]

The late medieval classic is causing me gray hairs.



I'm working on a weapon balance mod, cleaning up some of the oddities we're left with from the original Dominions days. There's something that's very puzzling to me.

Several troops in the game have glaives + shields. That makes no sense with a 2-h polearm, but more importantly, I don't understand how it's possible in the game anyway. The glaive looks like it's a 2h weapon, but still some troops manage to have shields with it. What's going on?
