Description:

A tag in the warhead, weapon, or projectile that allows the IronCurtain/Force Shield to be ignored. This should be very useful especially on AttachEffect type of superweapons where you 'buff' certain units.

Possible Implementation:

[SomeWeapon]
IronCurtain.Ignore=yes/no
ForceShield.Ignore=yes/no
