M104 Wolverine

The M104 Wolverine Heavy Assault Bridge was developed to give U.S. armored units an under-armor gap-crossing capability. GlobalSecurity lists Wolverine specifications, including its heavy assault bridge role, while Military Factory describes it as an M1 Abrams-based bridge layer adopted to replace older M60 AVLB systems. The bridging-system category is appropriate.

M104's design problem was straightforward: keep armored formations moving when they encounter rivers, ditches, canals, or blown bridges. Using an Abrams-derived chassis helped the bridge layer keep pace with heavy armor and survive in similar environments. The system's bridge length and load capacity determined what gaps and vehicles it could support.

Combat engineers are essential to maneuver warfare. A bridge layer like M104 preserves tempo, reduces bottlenecks, and lets commanders exploit breakthroughs. Its constraints include high cost, small fleet size, maintenance burden, and vulnerability while deploying the bridge if not protected by security forces.
