The M1074 Joint Assault Bridge System (JAB, JABS) is an American armored military engineering vehicle based on the Abrams M1A1 main battle tank chassis.[8]: p.154  The M1074 was designed by Leonardo DRS for the U.S. Army and Marine Corps to provide deployable bridge capability for units engaged in military operations.[1]

The bridge is an armored vehicle-launched bridge (AVLB) Military Load Class 95 Scissor Bridge (MLC95) is currently being replaced with the Heavy Assault Scissor Bridge (HASB) MLC 115.[9] After the M1074 has deployed the bridge, assault force vehicles can cross over the bridge. The M1074 can cross over, pick up the bridge on the far bank and continue along in support of assault forces.

    • By Modernization priority
    • By Acquisition or Business System category (ACAT or BSC). The Weapon systems in each ACAT are sorted alphabetically by Weapon system name. Each weapon system might also be in several variants (Lettered); a weapon system's variants might be severally and simultaneously in the following phases of its Life Cycle, namely — °Materiel Solution Analysis; °Technology Maturation & Risk Reduction; °Engineering & Manufacturing Development; °Production & Deployment; °Operations & Support
