Changing Unit Stats by event?

[porta80]

Hi i like to change Navy Stats, to make them more unique for each country by event.

for example: for germany it looks like this

########################### 45041 Kriegsmarine
event = {
id = 45041
random = no
country = ger

trigger = { }

name = "Kriegsmarine"
desc = "The Kriegsmarine was leader in submarine tactics and produced vessels like the excellent Bismarck class battleship. On the other hand, the ships were plagued by problems with mechanical reliability."
style = 0
picture = "ger_45041_scharnorst" #Steffele

date = { day = 2 month = january year = 1936 }
offset = 1
deathdate = { day = 29 month = may year = 1954 }

action_a = {
name = "Outstanding"
ai_chance = 100

command = { type = naval_defense which = battleship value = 2 } # superior comparmentation
command = { type = naval_attack which = battleship value = 3 } # superior main battery fire control + Throw weight
command = { type = shore_attack which = battleship value = 1 } # Throw weight
command = { type = speed which = battleship value = 2 } # Fast
command = { type = max_positioning which = battleship value = 0.02 }
command = { type = min_positioning which = battleship value = 0.02 }
command = { type = morale which = battleship value = -5 } # Poor reliability
command = { type = range which = battleship value = -500 } # Low range
command = { type = build_cost which = battleship where = relative value = 5 } # Big
command = { type = fuel_consumption which = battleship value = 0.2 } # poor fuel economy
command = { type = supply_consumption which = battleship value = 0.3 }
}
}

but it doesnt work for the stats which i like to change, only build cost works and the positioning.

any ideas?

thanks
