He's pointing out that T1 submarines include the category T1SUBMARINE, T2 submarines have the category T2SUBMARINE, but the T3 submarine doesnt have a category T3SUBMARINE.

Depending on the reason for wanting it, you could still achieve something similar by looking for units that contain both the TECH3 category and the SUBMERSIBLE category, while if you wanted to then exclude the t3 nuke subs you could exclude the category NUKE.

@tankenabard unfortunately no. The best advice I can give you is to look at others code.
Get a couple of simple mods, the simpler the better, then see what it takes to get a simple mod going.
Then find a mod or map that disables certain units - that will show you how it's done.
Then all you need is to apply and tweak the code to your needs and wants <-- that's the part nobody can help you with 😕

This could be done with a mod & could be done with a check of the player type to determine if the player is human or AI, so there would be no restriction on human players & AIs having the same faction, only humans having access to all the structures & units that the AI has access to.

I would suggest making a mod request thread in the Modding & Tools sub-forum.

I agree it's never great and I never get it basically, but there is a use case in holding a hard point under static shields.

I agree with the Mercy being a stun weapon. That's a cool idea.

Alternatively, maybe it could just do incredible damage, like 30,000, but only against shields. Similar to the rarely used t3 hover unit.
