Actually we don't have to find another officer - the fact German arms industry did indeed supply AP shells for the guns indicate they intended them to have an extra role.
The maxim is: "Proof of capability is proof of intent." The curious thing is that while "capability" may be present, as in the case of the British 2 pounder gun and its explosive grenade rounds that were available during the Battle of France in 1940 and in North Africa in 1941-1943, we have the exception which proved the rule.
The British, you would have thought, would have used this high explosive shell capacity of their 2 pounder guns to counter 88 / 56 or even 50 / 60 and 37 / 50 AT gum gun lines that Rommel's units set up as traps for British armored units? It is logical that high explosive shells be used against rather vulnerable AT guns exposed in open topped gun pits?
Not so. With the even larger bore diameter 57 / 60 (6 pounder) AT guns, the British army tankers persisted in using "slugs" and ignored the HE rounds that British ordnance supplied them for anti-soft target work.
Why?
Politics. British service branches had a pernicious exclusionary roles and missions rivalry, that makes the American army and Marines rivalry look like a fraternal comradery fest.
This curious rivalry was especially intense between the "Royal" artillery and the rest of the British army. You will notice that the term "Royal" was applied to the artillery? That bit of title shared with the other exclusive "club", the Royal Engineers, made the artillery branch a bunch of snobs who insisted that THEY be the ones who handled such missions as
"counterbattery" as an exclusive branch mission.
Well, okay, the British army could live with that if the British armor could RELY on call fires from the British gunners to the rear to suppress a suddenly discovered ambush AT gun line. It was only necessary for the British tanker to forward observe fall of shot and for the tankers to pull back so the barrage could be laid on, right?
Well... there was a PROBLEM. The "capability" was not there, though the "intent" was
doctrinal. The British logic, at least in the desert army, was
that a 25 pounder gun in indirect fire threw a much bigger grenade much further than a 2 pounder or 6 pounder gun in direct fire. True, so the German AT gun should have been neutralized with WWI British artillery methods. Right? The problem is that the British tankers had to forward observe and correct fall os shots out
since it was indirect fire, and they were
not trained to do it, nor were they equipped with
a common radio that interconnected with the wired in British artillery battery director networks.
That is right, the British tankers could not easily pick up a mike and say: "Hey, Jocko, I need you to lay some berries on mapgrid such and such, pronto. Jerry has some can openers that need breaking right away, old boy."
==============================================================================
You would think the Royal Artillery would fix this? Keep the mission, fix the radio net problem (As in creating ONE) and train the British tankers to be their eyes, and who knows, maybe train the British infantry to do it, too?
Nope.
If he was not Royal Artillery, he had no business calling in fires over the wire, or the newfangled radio. Our mission, lads. You just stick to your knitting and let us handle the complicated mathematical stuff.
===============================================================================
THAT changed.
American tank gunner's quadrant for the gun howitzer on a Sherman tank
Not only did the British tankers have to learn how to drive and shoot the right way, but they were introduced to interoperative radios and
THE GUNNER'S QUADRANT and how to use it to indirect fire the 75 / 40 with in support of British infantry.
MONTGOMERY insisted on it.
It was a way the Sherman could be used to fight as artillery as the French derived 75 /40 tended to LOB shells a bit more than the higher velocity British 6 pounder guns in common use just before 2nd El Alamein. The 75 / 40 was, by American doctrine and capability, supposed to kill infantry and enemy artillery, both in indirect fire and direct fire. The tank killing was part of the overall package and not the sole or even the main tank mission. Furthermore, thanks to experiments and wargames, the Americans had worked out how a private could be trained to call back to an artillery battery director and lay on indirect fires from a MAP to that battery director. Not only could howitzers be so employed under such direction, but TANKS and antitank guns, AAA guns, and anything else which could be indirect fired and gridded in on the enemy to be removed at map coordinates 12345678. It was HOW the Germans were finally stopped at Kasserine pass when
British infantry (Actually Americans embedded within the unit, because the British of 1st Army had not learned how... M.) called in indirect fires to American artillery and tanks posted to backstop them at the final line of defense.
The Germans did not figure the every gun within range of enemy called in by PVT Smith method either. At places like Mortain in France in 1944,
it cost them dearly.
=====================================================
It was common sense to provide AA-guns with AP ammunition; those guns fire at highvelocity giving them a flat trajectory which is well suited to combat Aircraft as well as AFV.
Which the British did as well as the Germans, but as with the Royal Artillery myopia earlier, one did not see the British use the rather good 3.7 inch AAA gun in the same fashion as the German 88 / 56, anywhere near as often, possibly because the heavier British 94 mm bore gun was a bit more awkward and less mobile and the mount was even more AAA centric specialized than either the American 90 or German 88.
The Danish Army didn't have men in Spain besides the volunteers for the International Brigades and a Lieutenant or two on the Fascist side but the Danish Army DID provide its 75mm Vickers AA-guns with AP ammunition and they did form part of the intended AT-defence of battle - as the last ditch defence as the guns had another important mission too!
That I did not know. Thanks.
So a lot of men had the idea some to even provide the guns with the needed rounds but it was so widespread You can't make Rommel the genius.
But getting the general idea past the institutionalized inertia of; "This is how we do things, because it is our role and mission" remained and remains a problem for most militaries.
I do agree that Rommel used what he had, the way he did, because
that was German doctrine. But not even the Germans figured everything mechanically out. In this they were like anyone else. They overlooked obvious methods and means such as interoperable radio and reconnaissance and plot fires by mapgrid zero and premeasured rulers from that survey point to landmark or grid coordinate for impactors as read off topo maps. Then thumb through your firing table books for charge loads and cranked in elevations, and then fire for spot, wait for the observers to call you for overs and shorts and then once corrected, "Fire for effect".
Just as a coda...
If you had to rate artillery performance in North Africa before the Americans arrived?
1. Italians.
2. French
3. British
4. Germans.
The Italians lacked radios, but they had that every gun in range on target tied into their network thing down pat, and everybody from a senior sergeant up, could get on the field telephone and call it in off a landmark or a mapgrid
if they had a decent map. The British and the Germans insisted on trained officers and trig on the spot at the firing battery. This surprised the Americans who got a very nasty Italian mirror image of themselves in Tunisia but were thankful that the Germans were a bit technique backward, as the German equipment was good, but application was lacking in simplifed callfire methods or in assigned guns numbers that could be massed onto a target.
