What its author says it does

Copied from the file, not written here

Crawls forward fast and low like a military high-crawl, driving hard on hands and knees, via a low translating sequence. Use when a command mentions power crawl, fast crawl, military high crawl, combat crawl on hands and knees, or drive forward low.

power-crawl

A fast, driving hands-and-knees crawl, body low and quick (root.y~-0.5).

Composes: move-arm + move-leg + move-torso

How

Use a sequence with loop:false. Frame root is ABSOLUTE; compute the travel axis from state.position+state.faceDeg (0=+Z, 90=+X). The example assumes origin facing +Z.
Torso forward (Spine+X~50); punch opposite hand and knee forward each beat; keep it quick.
durationMs ~2400.

Limits & posture

Keep ≥1 foot grounded except at a jump's airborne apex; stay inside human joint ranges and keep weight over the support — see balance-and-posture.
