I´ve been thinking about a feature that allows you to sell military hardware to other countries that don´t have something in their doctrine, like let´s say I´m Pakistan and want T 90 tanks but don´t have them in my doctrine, so I buy them from Russia. In this feature, however, you need to have researched something on the same level to buy a T 90, so I need to research the M1A2 Abrams to buy the T 90. I´m saying that you can sell all units that are vehicles, no infantry or officers, cuz selling humans isn´t good.
