In my reading time in recent days, I have been enjoying a good one that Sancho loaned me. Its called "ANGELS ZERO by Robert Brulle. It’s the one fighter-bomber pilot’s story of his role in WW2 in Europe between mid-June 44- wars end. Bob flew P-47's the duration of the war with IX TAC (9th Air Force). This is a highly recommended read for of us, not just the P-47 nuts, or the allied nuts.
On to the subject. I found this very interesting. I am going to just quote it straight from the book for you all to read.
After D-day, and a foothold was established in France, the pilot had a chance to inspect some rubble and damaged locomotives once they were moved to a temp field in France.
"We first noted that the cab (of the locomotive) had two inch thick steel plates welded around it to protect the engineer. It was obviously not armor as several 50 cal bullets had pierced it. I also followed the path of a 50 cal API round that went through the steel drive wheel several inches thick, ricocheted off the lower flange of the engine I-beam structure, and imbedded itself sideways in the upper flange. I had a hard time prying the round out for a souvenir, and it didn’t have a scratch on it. It was an amazing revelation of the power of a single armor-piercing round"
"A tiger tank was disabled by repeated strafing, and twelve trucks and a staff car were destroyed.
The reader may wonder how strafing a tank could disable it. Recall that our .50 cal API rounds pack a wallop that could penetrate several inches of soft (not hardened) steel. (Recall the story on our visit to the Laon railroad yard, where I followed the path of a .50 cal API round that went through a locomotives drive wheel.) During the war, we thought the penetration power of our API round was sufficient to disable a tank by shooting off the tracks. To research the issue and keep the record factual, I contacted several armored vehicle historians and specialists. Their collective views are summarized below*.
The .50 API round fired from fast moving AC does indeed have a high momentum but the German tank armor was very hard and massive and the round only dinged the armor. The most vulnerable area (least armor thickness) is the rear deck compartment and the top of the turret. The tracks are extremely hard steel and .50 API were shrugged off with little damage. A lucky hit was possible that might cause the tank to throw a track, but if they were on a hard surface they could keep moving on the road wheels. The Germans in 1944-45 had three main battle tanks in use. They were the Mark IV, which was a medium tank comparable to the American M4 Sherman tank, and two 50-plus-ton heavy tanks, the mark V Panther and the Mark VI Tiger. The Panther and the Tiger completely dominated the Sherman.
The Mark IV had a lightly armored rear deck that could be penetrated with our 50 API rounds and set the engine on fire, but the panther and the Tiger were mostly impervious to our strafing. In those tanks the crews would just button up and hope that we wouldn’t call in AC that had bombs since that would finish them. There is a case on record where a Panther tank was strafed by P-47's for an extended time. The massive strafing shot off all the equipment parts carried outside the tank, and entombed the crew by dinging the hatch lips, effectively welding the hatches closed. If we could catch the tanks while on a road march far from the front lines they sometimes-carried extra fuel and ammunition strapped on the outside. In those cases strafing could ignite the fuel or ammunition, possibly destroying them. Although we couldn’t be sure of damaging or destroying a heavy tank, our strafing was sure to affect the crew psychologically, having to stay cooped up hearing the constant rattle of our rounds hitting the tank and not knowing when a bomb or other heavy gun would finish them off. In summary, strafing a tank could do nothing or it could destroy them, depending on the circumstances.”

Brulle is a good author, telling it like it was for a “Jabo” pilot in the days after D-day and through the war. I suggest it to all that enjoy WW2 aviation books.
