After 13 grueling weeks, which ended with a 54-hour final test of the mind and body, Samuel D. Folan can now be called a U.S. Marine.

According to The Sun Chronicle, Folan, a 2011 graduate of Willow Hill High School in Sudbury, earned the title after graduating from recruit training at Marine Corps Recruit Depot in Parris Island, S.C.

The training is some of the world's most demanding entry-level military training developed to transform civilians into Marines, instilled with pride, discipline and the core values of honor, courage and commitment.

Training subjects included close-order drill, marksmanship with an M-16A4 rifle, physical fitness, martial arts, swimming, military history, customs and courtesies.

One week before graduation, Folan endured the final test called The Crucible. Upon completion, recruits are presented the Marine Corps emblem and called Marines for the first time.
