Since we are sharing our grandfather's stories and they don't need necessarily to be from WWII here's one from my grandfather who was a medic in the Portuguese Colonial War (1961-1974) wich is quite an unknow conflict but at the same time very brutal, it was a sort of portuguese stile Vietnam with three major fronts, Angola, Mozambique and Guinea-Bissau.
My grandfather told me that portuguese fighter pilots flew hundreds of ground attack sorties during the war.
One of the stories he tells me is when his company was pinned down by a group of rebels,armed with mortars,who were entrenched in a cave on a mountain and so they called for an airstrike and the the pilot managed to place a rocket inside the cave thus wiping out all resistance in one shot.
