All military chevrons point vertical it originated during ancient times when only males were allowed to be in the military. The chevron is a representation of the male penis signifying war was for males only. The higher your rank the more chevrons indicating the more manly and better warrior u were.
The short answer is yes and no. The Army and the Marine Corps have a very similar rank structure, with all enlisted ranks displaying chevrons, with the exception of Privates (E-1 in both services, no markings) and Specialist (E-4 in the Army, similar in look to a parachute). The Navy uses chevrons in enlisted ranks E-4 through E-6, however the chevrons are inverted with the point directed down. The Airforce uses chevrons in enlisted ranks E-7 through E-9. So yes the military uses chevrons in all branches, but some are inverted, and are not applied to all ranks.
Are you referring to the stripes by their cuffs, or the "rockers" under their chevrons? Rockers in conjunction with chevrons signify ranking. The stripes on their cuffs signify years of service. One stripe is equal to four years of continued service. Two stripes indicates the Marine has been in active service for no less than eight years, but less than twelve.
Each stripe is given for four years of service. That soldier (who was probably a Marine) has served for atleast 12 years. Or do you mean the chevrons on his shoulder. In which case would be rank. Three chevrons is a sergeant.
Corporal (2 chevrons) is right below Sergeant (3 chevrons).
Corporal
They are both VERY different. A Navy servicemen is in the Navy. A Marine is in the Marine Corps. The Marine Corps is just a department of the Navy.
