Drop Troops Ability?

[jc173]

I want to sort of differentiate between a cargo carrying ship and an assault ship. I was trying to come up with a troop launching component similar to a fighter bay. In my mind I think of a planetary assault as been carried out by drop ships or drop capsules or shuttles etc so I think it would be more realistic to somehow limit how many troops are dropped by tying it to a component. I suppose it could work as it is implemented now if the entire troop ship landed.
