ANY mobilization in support of OIF/OEF should qualify for exemption from the five year limit. It's possible that a few specialty ADSW type jobs far removed from anything operational might be questionable.

Also you can usually arrange for VOL orders to be written INVOL after making a handshake deal. It doesn't cost the DoD anything to write them INVOL...the navy is automatically doing that now anyway, for this very reason.

Check with your chain, see if the orders can be INVOL. Also check with the USEERA folks to find out what the exact wording should be.

Bottom line, it should not be too difficult.

However...by MPA do you mean Navy MPRA? If so, the navy will go to great lengths to ensure that selected reservists DO NOT get anywhere near 20 years cumulative AD. They will not let you go on any sort of AD after you hit 18 years. Other services do not necessarily have this restriction.
