 I'm Second Lieutenant Nicholas Rivera, I'm the platoon commander of medium girder bridge platoon at Bridge Company 9PSP. I'm a 1302's command engineer officer. In 9th Engineer Support Battalion, we have a standard bridging company which builds the medium girder bridge and the improved ribbon bridge. I'm Staff Sergeant Green, I'm the platoon sergeant for MGB Platoon Bridge Company 9PSP in 1371. We provide mobility to the MLG and the MAGTAP as a whole, enabling wheeled track vehicles and personnel in order to get across various types of gaps. A non-standard bridge is any bridge that is not either the medium girder bridge, the standard bridges for the Marine Corps and the IRB. In the other category we have non-standard bridging, which is taking the readily available materials, whether it's timber, concrete, something as basic as trees and dirt, sandbags, hasco. Whatever it is that we have available, we identify as needed for that gap. We can employ that to cross wheeled track vehicles, or in this case, to mobile personnel. A unit having the capability to build a non-standard bridge gives them a lot of leeway where the standard bridges for the Marine Corps either don't fit the capabilities or their mission requirements of what we need to do.
