This figurines represent an undead Landsknetch army. They don't have weapons because they are supplied separately.
Painted figures can be seen in Totentaz Miniatures' website (link below):

All the metal parts were sculpted by myself and copied to speed up the process except the Halberd who is sculpted by Angel Terol for Totentanz Miniatures.
