Combining combat deployments for overseas service bar?

I spent 3 months in support of Operation Enduring Freedom (Afghanistan) and 5 months in support of Operation Inherent Resolve (Iraq). I was wondering if I can combine those two deployments in order to be eligible for an overseas service bar. I looked in the regulation as far as being allowed to combine combat deployments in order to reach that 6 month period and includes Operation Enduring Freedom but does not say anything about OIR. I was wondering if the regulation is slightly outdated and OIR is included in this stipulation.

Thank you for all the input.
