Mm.OkI was saying the duck and cover at long range is unlike WB, for one because the stance and footwork is the exact opposite. The fighting strategy and tactics are contradictory at long and close range between WB and VT.
The cover using a single arm is familiar to WB, but exists in many TCMAs totally unrelated and predating WB.
To say it came "straight from" WB is like saying the VT dang-geuk came straight from MT.
It just shows an ignorance of Martial Arts of the world in general.
