There is always Bruneval. Major Frost of Arnheim fame was one of the priniciple officers on what was the first big commando raid of the war into France. This raid was a parachute drop onto the Würtzburg radar station at Bruneval France. The objective was to grab the critical components of this radar for study.
The raiders were successful after a small firefight and escaped by sea in landing craft. The results were the British came up with successful jamming techniques for German fire control radar and as an added bonus the Germans began to heavily fortify radar stations along the Atlantic wall afterwards. This made finding what before were very hard to spot installations almost immediately visible from the air.
