Well, I’m not sure exactly how they had implemented it, but I know (based on experience) that colder environments tend to make them harder to lock on with IR missiles.
For traditional radiator controlled engines, your thermostat will be cycling the same temperature fluid once it’s up to temp unless it’s so cold outside it can’t get/maintain the thermostat to open fully, or so hot that the radiator is in over temp regardless of OAT
For Turbine engines, they’re mostly. Maintained by some sort of engine control module that keeps them running at about the same temp most of the time.
The only real difference will be the difference between them and the surrounding conditions.
You are more or less correct. In cold weather a IR seeker will be more effective. WT has just badly implemented / coded them, especially in regards to non HIRSS equipped helicopters.
Move it to 9.7 and you got no lineup besides the TOW wiesel and the stinger wiesel/stinger gepard. No MBT whatsoever unless you uptier Germany 9.3 or uptier 9.7 tanks to 10.0 for leo 2k
The only way you can kill it when it’s hull down is HE, but if you don’t have that then you have to use HEATFS (which is less reliable), or you have to shoot its ATGM before they shoot it.
