I think it does when Marine jets launch from a carrier. When Marine Expeditionary Forces deploy, their fighter wings are deployed on Navy carriers. When Marine pilots do rotations through Carrier Air Wings I would guess they have to learn the ATFLIR, but when an entire Marine squadron deploys to a carrier I can't imagine they all retrain to ATFLIR.The question is will ED allow it to be added to the jet if you are launching from a carrier? In the real world that apparently does not occur.
That said, ED would probably allow it even if it was slightly unrealistic. At least until ATFLIR is in the game. If server admins/mission makers want to enforce that level of realism they could.
