Apparently, Flame Tanks exist since NSB. Dors anyokr know what "ID" (like fighter for Fighters)I have to use in a national spirit so that they get buffed?

It seems the unit names are:

light_flame_tank

medium_flame_tank

heavy_flame_tank

I would assume the prefix depends on which type of chassis you put the flame tank on.

So can I just use:

light_flame_tank_attack_factor = 0.1

for example?

I would assume so, although I haven't tested it myself

ok, thanks for helping, I'll try it out myself then!
