While never a serious threat, the Me-262 did see combat. Chuck Yeager, first pilot to exceed the speed of sound, was a P-51 pilot in WWII, and was the first American to shoot one down
as did the AR-234 against the Ludendorf Bridge at Remagan. in germany in '75 we heard our M60A1s w/105mm were inferior to shorter T-62s w/115mm gun. while true on size and gun we could depress the gun further and thus make better use of terrain for hide positions. we also carried more ammo with a better fire cotrol system.
