I understand Arrowhead has a new campaign but am wondering if the stock Arma 2 cmpgn is also there. Same for Reinforcements, I knowthere's new cmpgns for BAF and PMC

Thank-you for any guidance

I'm hoping not, that would be very very silly since the A2 campaign requires the arma 2 maps and units.

For the a2 campaign, you need a2.
For the OA campaign, you need OA.
For the BAF/PMC campaign, you need BAF/PMC or RFT.
