Not all National Units have the same quantity allowed. Inquisitor has a base limit of 3, while Freight has a base limit of 5. I don't think we need to change this.
Clones should definitely be capturable. I don't know about Mobile Artillery; I think Modern Era siege units could mark the transition between weapons that are easy to turn on their former owners and weapons that don't work if captured. If someone else gives you the weapon and the specific information to use it, that's different from capturing it on the battlefield.
