Part of the standard issue US Molle II system: this holds the standard entrenching tool, aka shovel.
These are in ACU/UCP (that grey digital camo that blends in with a gravel pit and grandma's couch)
We also sell the shovels, though they are sold separately.
These feature a flap closure with plastic buckle, and two molle straps on the back.
These will be from a variety of makers, but all are genuine US Government issue and in excellent shape.
