With his international outlook, his concrete experience of the everyday life of the war and his great work capacity, Raab was one of the Swedish Army's foremost officers during the 19th century. Raab was educated at the Royal War Academy from 1847 to 1850 and was commissioned as an officer in Kalmar Regiment with the rank of underlöjtnant the same year.
