Specification

DEFINITIONS
Lightly Bogged Vehicle
A vehicle that is experiencing minimal loss of traction, typically with one or more wheels spinning but with no significant sinking into the surface. Little to no chassis contact with the ground, Minor wheel spin because of slippery or wet surfaces. (Applied force = 25% of GVM)
Medium Bogged Vehicle
A vehicle that is partially stuck, with moderate loss of traction and some sinking into soft terrain (e.g., mud, sand, snow), potentially requiring assistance. Some chassis or axle contact with the ground, multiple wheels spinning. (Applied force = 50% of GVM)
Massively Bogged Vehicle
A vehicle that is deeply embedded in terrain with significant loss of mobility. Recovery is complex and requires substantial external effort. Chassis or axles buried, All wheels lack of traction. (Applied force = 120% of GVM)
