No need. Go to the console. There should be a big box on the top and 3 long horizontal boxes at the bottom.
1. at one of the long horizontal box type "jna_datalist", a long list of whatever you have in the VA should show up.
2. Copy the list to notepad, Edit the list to whatever you want in the VA. After you done, Copy it.
3. Go back to the console. In the top big box, type:
jna_datalist = (paste what you just edit)
4. Local Exec.
5. Done!

If you haven't figured it out yet, when you paste it in Notepad you'll see the whole list of all the items. Unfortunately it's mostly just the file names rather than easy-to-read names, like "SMG_01_F" and stuff. If you wanted to remove that (I believe that's the Vector SMG), then delete the whole bracket:

["SMG_01_F",-1],

Remember to delete the comma (,) after the bracket as well if there is one. If it's the last item in the list then there wouldn't be a comma.

Ok how to change uniform of AI squads? do i update the arsenal or not to do that?
