Late in June, 1st Battalion, 9th Marines, out of Camp Lejeune, N.C., will participate in three physical testing events:
• A replica 40mm Mark-19 machine-gun lift, in which a Marine lifts a 72-pound weapon over his or her head while wearing a 71-pound combat load.
• A casualty evacuation, in which a Marine drags a 165-pound mannequin wearing a 43-pound combat load while wearing a 43-pound load of his own.
• A “march under load,” in which Marines carry a 71-pound combat load 20 kilometers in less than five hours.
Infantry units do this all the time. This is all they really do. They hump around, go to the field, and practice fighting wars. They come back for a few days, rest, clean weapons and gear and they go do it again.... for years. They are trained to be the individuals that are tasked with taking territory and holding it. They train to do this as combined arms units with support for the other combat arm mos's of artillery and tanks. They train with the support of air assets... and the rest of the training for the remaining Marine Corps is in logistics (how to supply these infantry units while on the move).
There is nothing "normal" about this. The infantry is the primary focus of the Marine Corps. Everything that everyone else does is to support the infantry. The physical standards and regular training regiment of these units is grueling and it never stops. You will always find that the small unit leaders within the infantry community are all the top performers in regards to these physical activities, in most cases the officers are the top performers. The Marine Corps is very focused on physical ability, physical performance on these tests factor into promotions and thus the advancement of careers.
As difficult as this is for infantryman, the physical standards for the special forces are even more intense. This is to include MARSOC, SEALS, RANGERS, DELTA...
