Can Hide in Long Grass

The Iovamann (Eev-ah-mun; "Fighters [out of necessity]") are formed from some of the poorest members of Lusotannan society, those who live off their flocks of sheep and goats at the top of the mountains of Lusitania. They are armed with several "sude", which is a wooden javelin, sharpened and fire-hardened on both ends. While this would seem ineffective, it can play havoc with lightly armoured enemies. They have only a coarse wool tunic for protection, so they are among the most vulnerable soldiers to cavalry or missile counterfire. Luckily, they have a nearly inhuman ability to hide in tall grass and thick terrain, allowing them to ambush enemy columns and seemingly disappear into thin air. They are armed only with a knife for melee, so they must be guarded from any hand to hand combat.

Historically, these warbands were the lightest and among the most 'annoying' harassment troops that the Romans had to deal with. They caused many casualties before they retired back into the night or hills and attacked again the following day. When the Romans imported good light cavalry to help in their wars against the Iberian tribes, their job got a whole lot harder!
