Question about the army?

Your plan sounds find. Just know that during your initial training you won't be allowed to do any of that. Afterwords you'll be good to go, though.

You do not want to join the Army. It will tear you down until you stop questioning orders, chew you up until you can't bleed any more for your country, then throw you away if your existance becomes less than convenient. An old Army slogan used to be "We do more before 9AM than most people do all day." The modern version: "Our gate guards get paid more by 9AM than we do all day."

Bear in mind that what you sign up to do in the Army is no promise you will do that job. You'll be graded as if you were doing that job for promotion opportunities, but few people in the Army outside of infantry and military police actually do the job they signed up for on a regular basis. You will do whatever your unit needs you for, regardless of your qualifications. A chemical soldier may get to spend one day a month checking gas masks and radiation equipment, and the rest of the month he is just another unskilled laborer. Other branches devote the time to training you that they would be wasting resources if they had you doing 'generic unskilled labor' when you could be doing your job.

Join the Air Force, Navy, Marines or Coast Guard. Their quality of life is exponentially better than that of the Army.

Medical care is a factor I use to demonstrate the differences.

In the Air Force, your doctors are highly paid civilian contractors. There is a long and highly competitive waiting list to work for the Air Force as a doctor and the quality of care shows. To join the Air Force as a doctor, you have to already be established with a track record of success.

In the Navy, your doctors are actual Navy personnel. They will take care of you because you're a fellow seaman. They put on the uniform, take the PT test and fire their rifles the same as everyone else, so they know what you do on a daily basis and are going to ensure you get proper time to recover if you get hurt. Marines get to use Navy doctors.

In the Army, your doctors fall into two categories. Since the Army pays very little, you have either foreign nationals on work visas or doctors whose track record is so horrible no civilian establishment would hire them (Army doctors can't be sued for malpractice no matter how badly they screw up).

The other branches of the military care for their people, seek to advance them and leave them better off than when they first joined. The Army just wants to bleed you dry and throw you away. Remember that "Veteran" is not a protected class under Equal Opportunity laws, and employers generally view Army service as a negative factor.

After training you can wear some make-up, have a real or fake tan, and wear your hair accoundinly to the Regulation

You are not going to need a fake tan in the Middle East or central Asia nature will take care of that.
