So I have this new concept of a map I'm working on where I need to spawn units and have them go on strategic Suicide Missions but whenever a new unit spawns after the strategic suicide mission has been executed it's like it isn't even controlled, it doesn't move. I tried making Strategic suicide missions run every time the unit spawns but that doesn't do anything either.

I've seen it done before though on the Random Micro Challenges where new enemies are spawning but always have an ai controlling them, it's just not working for me. Solutions?

I'm not very experienced with AI Scripts but here's what comes into my mind reading your problem:

Things you should check:
The suicide mission AIs can only be executed for comps. (Is it running for the right comp?)
The comp needs an enemy. Placing another comp in another force DOESN'T make them enemies. Use Alliances action.

Things you could try:
Also you could try to change between AIs (random vs. strategic)
Try different locations: Everywhere vs. Spawn Location
