text: should i join the airforce of the coast guard? i'm a college grad and want to know what knowledge people may have gained from experience with either one. first, since you are a college graduate, i highly recommend you enter military service as an officer versus as an enlisted member.  they pay is 30 to 40% higher if you are an officer.  second, i recommend the air force.  i was in for 10 years and enjoy it.  i am biased and i know very little about the coast guard.  third, ensure the military training you are going to receive can be transferred to the "civilian world".  you will have to leave military service one day.  makes sure your talents are transferable.  good luck
