Throughout military history, the gear our ground troops wear has depended on different aspects, for instance: the available technology, budget, and the weather (for the most part).
The needs of the mission and the environment determine what gear our infantrymen haul on their backs, around their waists, and even what they stuff into their many cargo pockets.
But the endgame of the mission always remains the same — win the war at all cost.
Today, the modern battlefield of Iraq and Afghanistan has prompted our military to change what our troops take with them. "SAPI" plates (Small Arms Protective Insert) were added to help protect the service members vital organs from small arms fire.

Travel back in time where medieval Knights wore several layers and different types of heavy body armor to protect themselves from sharp swinging swords to the accurately shot arrows. These fearless men would spend countless hours training while cloaked in their protective garments, acclimating their bodies for war.
Fast forward to the rice patties of Vietnam where Marines, Sailors, Airmen, and Soldiers bravely left the wire typically sporting only their thin layered green t-shirts due to the constant humidity of the jungle while still toting pounds of extras.
One 155-pound TV show host wanted to experience just how heavy the gear of an American GI in Vietnam was. So after donning the full Vietnam War style combat load — complete with ammo, an M-16 rifle, an individual medical bag, and 2 quarts of water — the TV show host's total weight amounted to just under 235 solid pounds of gear. It was an 80-pound difference.
