how many dollars is paid a fighter isis? is there any source about this?
According to this
http://www.iraqinews.com/features/isis-abu-bakr-al-baghdadi-grants-1200-house-furnishings-members-wish-marry/"The Syrian Observatory for Human Rights had published earlier that the monthly salaries given to the fighters of ISIS distributed as follows:
The Syrian fighter earns a monthly salary of $400. The Syrian married fighter gets an amount of $ 50 for each child, $100 for each wife, in addition to the basic monthly salary of $400, as well as providing a house if the fighter does not have a place to live, fuel for his car from gas stations which are managed by the organization of ISIS in addition to receiving fuel for heating."
But as I heard a part of their income comes from looting.
The bad news: ISIS don't paying pension and life insurance
.
$400 should be reasonably good money in a developing country.
$100 per wife is an incentive for Syrians to take as many wives as they can. I am sure there will be an upper limit.
