There's no such thing as a glavie! it's called a GLAIVE:
http://en.wikipedia.org/wiki/Glaive
A glaive is a polearm consisting of a single-edged blade on the end of a pole. It is similar to the Japanese naginata. However, instead of having a tang like a sword or naginata, the blade is affixed in a socket-shaft configuration similar to an axe head. Typically, the blade was around 18 inches (55 cm) long, on the end of a pole 6 or 7 feet (180-210 cm) long.
There's no such thing as a halbert, it's a HALBERD
http://en.wikipedia.org/wiki/Halberd
A halberd is a two-handed pole weapon that came to prominent use during the 14th and 15th centuries. The halberd consists of an axe blade topped with a spike mounted on a long shaft.
This drives me nuts just about every day since I've played tons of other games where they got it right.
