Army Winter Sports Association Patch

[ehrentitle]

Normally I'm in the US or DDR sections of this forum. But a few weeks ago I acquired a group of insignia of a US Army Sergeant Major which in addition to the normal US rank and unit patches included an unusual British patch which I believe belongs to the Army Winter Sports Association Patch. Can anyone here verify this? How difficult is this patch to find?

He also had Russian and Polish para wings so I assume he served in Bosnia or Kosovo where he could have come in contact with all of these forces and brought back the insignia as souvenirs.
