Adding Tanks to craft/ X-Com Files

[Rndl99]

This may be a stupid question, but I'm honestly stumped

I'm playing version 2.2 of X-Com Files, whether the mod is relevant or not, and as usual, most of the time I use only soldiers without any tanks/ai units/etc.
But after researching Gunship/AC, I got curious and wanted to play with that. Well, after multiple tries I have no idea how to add it to the craft. Tried with a standard launcher tank, and can't do it as well. Ammunition for tanks is visible on equip screen, but not the tanks. Skymarshal has HWP capacity of 4, so that should be enough, right?

What do I miss? Thanks. Some screens attached.

Aren't tanks equipped as 'suits' for AI, just like the drones are?  Haven't got tanks in my game so far, but I do known the AI (assembled from Shards) needs to 'put on' a drone in order for it to become an 'agent' and be put on a transport.

Oh, boy. Yep, that's it. If it's explained ingame, I have completely missed that. I thought AI is only for drones...

Anyway, thanks!
