1-I believe the ability is called pepper_pot. Since the British are programmed differently you may just want to change the ability or you could just add an unobtainable requirement with usage and display in order to hide it.
Well,the ability is called "churchill_crocodile"(Deploy a Churchill Crocodile flamethrower tank.)
not "pepper_pot" (Heavy supporting artillery will fire at the target location.) I'm afraid.
2-I have no idea how to change the ability.Could you show me an example?
3-I trier to add these requirements,but nothing changed:
"squad_type": is2 (need a IS2 squad to active the ability?)
race: soviet (this ability is not of soviet's ability)
"structure_name": refugee_female_mp (must have sovet refugee_female to active the ability?)
I'm not sure if they are unobtainable requirements.
4-I tried "display" , "usage" and "usage_and_display" on the same ability,but I don't see any change.What's the difference between them,may I ask?
