For the cost, these things rock because of there speed and anti-tank abilities. Typically, I use them to occupy space in the forest and hold my flanks. Furthermore, their 20mm counterpart (which is only 15 creds) are great at warding off inf and APC's. If either of these units can take out a few units, their sacrifice would not be in vain and provide a favorable trade off.
Speed doesn't really matter when this thing gets stranded in the open fields after 200km...
Drop the Command Jeep and replace it with the German highly armored thing (the M-unpronounceable-number -combination). I also never ever have placed an extra FOB. In most cases I delete my initial one, if I think that this will be a supply heavy game my initial one is more than enough.
If I'd be you I'd only use one command unit, but there are alot of very command heavy players out there. So that may be enough.
Arty is fine, but consider replacing one of your missile AAs by the Gepard. Which one you drop is a matter of taste, though the Chapparal is made for defensive players, while the Marder Roland is made for offensive players.
Stinger and Bradley is a nice AA/AT combination, but the SAS is horrible to my mind. If you use them for command hunting, why not take the Green Jackets, the 2eREP FAMAS or the Fernspäher? All of them have decent AT weapons. The SAS only has an incredibly bad AA weapon and is more expensive. The problem with the SAS is that they are rendered incorrect ingame. In reality those were the first to have Stingers. I don't know why Eugen gave them those awful Blowpipes.
