Are OEF, OIF, and ISAF different theaters of operations?

I, myself before RETIRING 35 YEARS, 7 COMBAT TOURS will tell you this, YES, ALL 3 mentioned is in facted 3 DIFFERENT OPERATIONS, 3 different countries, if any one tells you different, then ask them what type of DRUGS are you taking, because it's not working or it's the wrong drugs

Same Theatre but different countries or named operations within the same theatre. ISAF is just a named for an organization or command

OIF - Iraq OEF - Afghanistan ISAF - Afghanistan

Absolutely not the same theater. Iraq is flat, Afghanistan is not. The experiences in each are quite different. You can get by just knowing Arabic in Iraq, but would be fairly screwed if that was the only language skill you bring to the party in Afghanistan. Why your command would think two p,aces far removed from each other are the same theater begs additional questions.

I don't know both can suck to be at but I also miss them both! I'll let you know if I get to go back

OIF is differant than OEF and ISAF isn't a theather.

Theater on this context means location, so your command is right.

OIF and OEF are two different operational periods and define the country of the operations, ISAF defines the unit forces in theater

They are separate theaters. I served in OEF and OIF. The other is an international group of military members from around the world. They served in Afganistan and Iraq.
