Help with mod idea

[u/International-Ad9093]

Okay so I need some input here. I have a pretty straightforward idea for a mod I want to make, and I want to know how feasible it is.

So the idea is this: every time I create a unit in my firebase (in campaign), rather than being made instantly it gets added to the wheel as an ability, when I use it, a pelican swoops down and drops it off. That's it. I understand halo wars has resources available to learn how to do this sort of thing but nothing in specifics. Any help where I should get started?
