Find all the skirmishers.
1) Formation: 1.5, 1.5, 3, 3, 3.
2) Weapon: prec_javelin80 (this is important, 'javelin' is useless)
3) Range: 70/80 meters, as you wish.
4) My default number of javelins is 6 (sometimes lower). I lowered their attack to 6, from the previous 9.
5) animation chage - you can change it in
battle_models, to 'EB_Short_Javelin_Prec' as a primary weapon
5) ^if you don't know how to do it, change the EDU like that:
-'Euzonoi' soldier for javelin + knife/sword
-'kareus_late' soldier for javelin + overhand spear
-'Garamantes_Inf' soldier for javelin + underhand spear
I hope you get it, mate. One hour of work and your skirmishers are in the badass mode.
