The Level IV bulletproof plates were too heavy;, Yang Yi hefted one and felt that it must weigh nearly ten kilograms. With one on the front and one on the back, plus the extended groin guard, Yang Yi estimated that wearing the full set of heavy bulletproof vest would weigh at least twenty kilograms.
In contrast,, the Level III bulletproof plates were much lighter; one plate weighed only two to three kilograms, and a complete set of bulletproof vests weighed less than ten kilograms. Wearing it would hardly affect the team's mobility.
"Do we really need Level IV bulletproof vests? They're just too heavy when worn!"
Equipped with a heavy bulletproof vest, carrying a gun, a helmet, grenades, and various other items, the total load on one's body would be at least thirty kilograms. That was just with a SCAR-L rifle, three hundred rounds of ammunition, and four grenades. If one were to carry more ammunition, or add his Alexander rifle to the mix, the load would exceed forty kilograms.
