Oxy you playing Arma in a clan?
I really fancy that but couldn't get into it... i like the thought of true warfare! will the PR be better version of arma 2?
Yeh, I'm a member of rustyinplaces.org
There's a mod called A.C.E2 which everyone was waiting for which made things even more "real".
Arma2 is more co-op and people make there own missions, like my clan leader who makes wicked missions that are very hard. He uses a lot of British models so every Sunday night we play one of his as British Army with Land Rovers and Merlins etc
Arma2: PR is being made to address the pretty much non-existant (not strictly true) player vs player of arma2, which is when I suspect a lot of our PR platoon will play "Arma

R" and we will have a huge team.
Arma is really hard to play in public games/own your own. It's an awesome game, but has a high learning curve. I had to join RIP to understand it and am still learning now.
Apparently Bohemia Interactive, who make Arma really listen to the community and add parts of this ACE2 mod that the community makes into each release. I am told a lot of ACE1 on ARMA1 was made into the official Arma2 game, some of ACE2 mod is being added to the standalone "operation Arrowhead" game next month, like thermal imaging, proper targeting system for choppers/planes.
Our clan missions are designed to be done with a team of 10-15 so we usually use snatch land rovers or enter via parachute or Merlin drop-off.
We ain't large enough as an Arma2 platoon for full scale tank/APC/Apache/Harrier attacks.
The co-ordination on vent would be insane for us, we struggle keeping organised in 3 Land Rovers lol.
It is insane fun, but needs teamwork and planning.
Arma2 can be what ever you want it to be, full scale Airpower, sea or land, or SAS ninja style.
We seem to play missions SAS ninja style as a clan/platoon.
If you want to signup post on rustyinplaces.org its free for 30 days then £5 a month for server costs, as I say we play properly on Sunday nights but I train a lot in vechiles and learn a lot about ACE2 during the week.
