Lee Harvey was in the Marines, they have 3 rankings for rifle qualifications, from lowest to highest: Marksman, Sharpshooter & Expert. Most Marines have to qualify with their rifle every 2 years. Oswald first earned a Sharpshooter (2nd highest) in 1957. When he qualified again in 1959, he earned Marksman (3rd highest rank). He never earned Expert.
