The most imp question. How are NCOs and Soldiers treated by the Officers? Since in most of the Army. It's the tradition within to keep them below the thumb. Approach them with a grudge and they likely work at the Officer's house as well. Like paint jobs or gardening etc. Is that the same in Iranian Army? Are NCOs afraid of the Officers?
2: Is it possible for an NCO to get promoted through and reach to an Officer's rank? Like there is in Western Armies where priviates (Soldiers) can become Captain too. But its not possible in Pakistan Army. NCOs have their own Ranks. They may become a JCO but never an Officer. Unles they have enough qualification. They can separately apply to get commissioned and go through the testing and all the procedures.
3: What Incentives and Facilities does an Officer receives in the Iranian Armed Forces? Free Medical of Complete Family? (Including Mother and Father), A Batman (Servant paid by the Army), House (Issued by the Army) and Membership into Community and Sports Clubs run by the Army?
4: Upon getting retired. Do Officers receive any plot or a permanent house by the Army?
Regarding the first question, what you said on NCOs and officers relations were very true during the Shah times, there was a sea between NCOs and officers, today while the difference and somewhat a complex exists between officers and NCOs, it is much more smaller, well NCOs don't paint walls and work in officers houses but they are less privileged and paid than officers, but NCOs are scared of officers and don't have a lot of respect(unlike western armies).
2- NCOs can advance to officers rank(3rd Lt), it is either through getting a higher degree or reaching the last NCO rank(Ostovar yekom) and completing a training course.
3-Members(Officers,NCOs and conscripts) and their families(only professionals not conscripts) of Army, Revolutionary Guards and Police are covered by "Armed Forces Social Security Insurance", they receive the same treatment and services regardless of rank or service.
If they use armed forces medical facilities(Army, IRGC and Police have dozens of hospitals and clinics) , the health services are mostly free of charges, but in private institutions, the insurance pays a part of the cost.
Armed forces have their own sports clubs, swimming pools, restaurants and etc, regardless of their services they can uses these facilities.
Armed Forces personnel do have free residential complex called in Persian "Khaneh Sazmai", these are usually residential complexs separate from civilian population and under the guard of military police and jurisdiction, these complexes have their own schools and etc, these are free of charge for active members of armed forces and their families, retired personnel get no free housing(unless they are war veterans), the size of housing differs based on the size of the family, also Armed Forces corporation foundations(Bonyads) builds subsidized housing projects for Armed Forces personnel, and provides the personnel with low interest loans so most personnel upon retirement have their own houses.
There are no government paid servants for Armed Forces personnel in Iran although it existed under the shah, also Armed Forces have chain stores named "Etka" all around Iran, they get their monthly subsidized goods and food stuff from there, they can also buy a limited number of goods from these stores(like, TVs, refrigerator and etc) and pay for them from their salaries in one year or two year payments.
All Armed Forces services have their own banks which offers them services and loans.
4-yes, retired armed forces personnel receive fixed payments and insurance policy for life, the insurance policy extends to spouses and unmarried children of the retired personnel.
If the retired servicemen dies, his wife will receive the monthly salaries untill she is alive, this policy extends to unmarried female offsprings too.
Only veterans can use free housing after retirement, but as I said earlier armed forces Bonyads are always building new subsidized houses for personnel, each personnel can use these option one time in their service, and get their own house.
