There are stories from the Vietnam War about US Special Ops using silenced .22 rifles during prisoner snatches.
Reportedly, they'd set up on a trail and wait for a small unit to come through.
They'd pick out the one they thought was the officer and shoot him in the knee cap.
When he fell they'd trigger Claymore mines set to kill anyone standing up in the kill zone, grab the prisoner and extract.
They could tell who the officer was because they always needed to make themselves special somehow.
Usually the man with a pistol or tennis shoes a different color from everyone else was the officer.
