The uniform is a match for a Lithuanian army uniform, early 20th century. The collar symbol represents the Columns of Gediminas, which have a historic association with the Lithuanian region. Searching reveals some similar uniform photos with the same collar emblem being mentioned as 1920's to 30's, possible as late as 1939. I do not see any rank insignia on the shoulder boards, and sleeves are unfortunately not included in this image, so this individuals rank may have to remain a mystery.
