I am talking about this unit


I am really not an expert of iberian history, so i got quite shocked when first i read on the description of this unit that they did not use the falcata (similar to the gladius hispaniensis) as did most of the iberian tribes. In the game they are using a celtic long sword, i guess this is because of the influence of the celt culture on this iberian tribe.

As far as i know the ilergetes were culturally a iberian tribe with heavy greek influence from the colonies (emporion) and not so much celt influence. I was wondering why the ilergetes are given such a different swords, being still a iberian tribe i guessed they would have used a thrusting weapon along with the scutum, not a slashing sword. Is there any representation or evidences of this difference in equipment?

I also think the team could have done this to represent the influence of the celt culture on this tribe, but as i said earlier, i don´t really think that this tribe would have adopted the longsword. In the case they would have to fight a celt tribe, the use of a big shield like a scutum plus a thrusting sword like a falcata/gladius would me much more effective agaisnt opponents using long slashing baldes on close quarters. So then, why is this tribe depicted as using the celtic long sword instead of using, as other iberian tribes did, the falcata or a similar thrusting weapon?

Thank you in advance
