Arma II Operation Arrowhead mod advice

[Stealhead]

Hey guys I just picked up Arma II OA from Steam (on sale) anyway while I wait for it to down load I am lookinf for some good mods.

I do not have base Arma II so I am not looking for DayZ.

What I am after would be weapons mods I like my guns.I am looking for mods that add in weapons Like the FN FAL for example or the SCAR weapons things like this any weapons go AKs,M16s what ever the more the merrier.I would also be interested in any general "must have" type mods that improve the base game.

Also I have Arma and there is a mod that allows you to select weapons when ever you want to on the fly I used that alot messing around in Arma(playing single player). Is there anything similar for Arma II?

Thanks in advance for any suggestions.
