Some Modding Questíon Options

[TheRipper]

After the endless Firestorm Generator I continue modding my TS.

But I have some questions:

i want better infantry. searching for SHP, rules and art can be included, too
Can you give me a link?

How can the EMP Cannon modded to be an EMP Arty?

but the most important question is:

How can I do a "Ground Editing Vehicle"?

It should be able to make the hills to smooth ground.

Like the Ion Cannon or the Nod Arty.
