I specially agree at 1 and 6, though i fixed 6 in the editor, it takes a little time cause i also added realistic equipment but here it goes:
1, Spawn all units that wear boonies.
2, Click one of them.
3, Now when there are options for/about the units, like where you chose which player controls what. Go very down and find a small tab called "Breed", its right above "Skin".
Click on the [...] button next to it and now you're in a window with the title "Breed Editor".
4, Go down to hat and now click on the following (last time i did this was yesterday so i wont remember all that clearly or that good and some might be wrong).
Helmet1_US = M1 helmet with no extras and accessoirs.
Helmet2_US = M1 helmet with the legendary 'Nam mitchell camo.
Helmet3_US = M1 helmet with Mitchell Camo and a '65 insect repeller and a 5 bullet clip on the sites.
Helmet4_US = M1 helmet with Mitchell camo and a package of Malboro Cigs.
Helmet5_US = M1 helmet with Mitchell camo and a Poker Ace of Spades card (my personal favourite :3)
Helmet6_US = M1 helmet with Mitchell camo and a Sniper-Leaf-Camo
Helmet7 and Helmet8_US = Pilot helmets.
What i did was place every helmet in the Inventory tab on the ground next to my soldiers i edited and then click on them each time i was about to edit so i knew what helmet was what.
About the jet i got no help sadly, i tried putting every bomb available in the inventory and the F4 only shot with its guns. I guess the campaign bombings use special triggers when the F4 flys over the trigger it creats a Napalm explosion or 6 or 12 or 24 or 48 or 96 or so.
Glad to help if i helped at all
