Identification of uniform

[amirevan]

Could someone please help me identify the uniforms. The pictures are of my great grandfather,his brother and someone else I don't know. I also have scanned pictures of the details/insignia on their coats. I know nothing about my family. Maybe somebody can help me please? Thank you in advance.
