Skipping Leg Day | 15 cm sIG 33 auf Panzerkampfwagen I ohne Aufbau Ausf.B Sd.Kfz.101

Providing adequate fire support to an infantry unit was, and still is to this day vital in achieving success when engaging enemy positions. This is something that the Germans were quite aware of before the Second World War, based on their experience gained in the First World War. For destroying well-defended targets, they introduced the 15 cm (5.9 in)schwere Infanterie Geschütz (heavy infantry gun) 33 into service, or sIG 33 for short. While this gun did its job very well, it was heavy and hard to field. In order to increase its mobility, the Germans decided to mount this gun on a modified Panzer I chassis. Alkett was tasked with developing such a vehicle, which it did in 1940. A small production run of 38 vehicles would be carried out. Despite its primitive construction and the limited number built, this vehicle, very creatively named 15 cm sIG 33 auf Panzerkampfwagen I ohne Aufbau Ausf.B, would remain in service up to 1943.

[@paulthiessen6444]

Still mystifies me that they didn’t bother taking off the wheels.

[@George_M_]

Given later silly Waffentrager ideas, they probably had a mandate that the gun had to be dismountable.

[@jeffreypurcell4681]

The gun mount was designed so as the gun can be dismounted but it need a crane !

[@darronhedges5873]

I know,and the rudimentary fixing arrangement is medieval.

[@czwarty7878]

The idea was to still be able to dismount the gun and place it in dug-up defensive position etc.

[@czwarty7878]

@@George_M_ how is that silly? Since the carriages are weak, it's safer to shoot from dismount whenever possible, and allows to shoot from fortified emplacements in defense. Designs which were optimised for safe firing from carriage, like Grille, Wespe or Hummel didn't have dismount option added.

[@holung1772]

I have respect for anyone that can pronounce German tank names

[@jeremy28135]

2:12 Notice how the German artilleryman opens his mouth before the FIRE! signal . This was to distribute the force of the shock away from the eardrums and brain

[@JGCR59]

The 706th company ship being sunk in the adriatic means you could potentially recover some of them from the wreck if someone had the money to burn :)

[@holgernarrog962]

Probably scrap collector company`s did already recover the ship and its load after wwII.

[@genericpersonx333]

It is interesting how little attention the German infantry guns get during the Second World War, despite them being so important to German concepts of how to deal with problems encountered in the Great War, when it was determined a small section of specialized artillery able to directly fire in support of infantry rather than depending on area fire would have greatly helped deal with the many fortified positions and bunkers that became common fixtures of the more open battlefields of the war.

[@darronhedges5873]

I have a facsimile Artillery map with tracing paper overlay and fields of fire marked and scheduled for rolling barrages.Looks bloody confusing is an understatement.

[@genericpersonx333]

@@darronhedges5873 For sure. And Germans really didn't want to have to do that for everything when they could have more precise guns that could really put a few aimed shots more or less right on target rather than making the full-size howitzers do all the work all the time. Saved a lot of work for the big long-ranged howitzers by having these smaller guns on hand.

[@czwarty7878]

Yes! Very underrated and overshadowed by more "flashy" units, infantry guns were important as a very flexible asset. A quickly deployable set of guns at the ready to sling HE-shells at the instant, without having to wait to coordinate with artillery units in the rear, was a big advantage on the battlefield. You'll be hard pressed to ever see one in the movies, yet these guns were often mentioned by veterans as very effective whenever they encountered a strong target.

[@JeanLucCaptain]

Some with the Soviet SU series.

Just finished building the /35 dragon kit.I’ve built a few PzI”s and it’s such a slapdash design it borders the comical.KV1! No problem,send out the Big gun.

[@kurt5490]

The more I learn about this vehicle the more of an enigma it becomes. It truly could only exist in a certain point in time. Used as an offensive weapon against an enemy of mostly poorly trained and led infantry. Once supply lines were extended and the Russians were on the offensive, it became a liability. The sig 33 was abandoned in great numbers during the withdrawal from the Rhezev salient after the failed assault on Moscow. I couldn't imagine using this vehicle at point blank ranges against a competent enemy. That would be suicide.

[@JeanLucCaptain]

I can’t imagine using it at all it’s s huge target no real protection and it’s liable to break

[@terraflow__bryanburdo4547]

Big biceps, small calves.

[@mattw785]

Sounds like they built it with stuff from Home Depot lol

[@mattw785]

what a maintenance nightmare

[@kamikazesoviet]

Such a cool little tank with a big gun. Would you consider making a video that shows what kind of damage happens when a tank takes a hit? It would be interesting to see some examples of what exactly goes on, depending on the caliber, tank and type of round.

[@kawaiiarchive357]

I really like the Panzer II version, it looks way less dorky than the Panzer I.

[@Ralphieboy]

Great and informative film, I only knew this vehicle from film footage.

[@johnlansing2902]

We will station you in a vehicle , behind paper thin armorer , very tall and easy to see , in a area where you will break down most of the time , firing a weapon that draws maximum attention from the enemy ! Great sign me up sir .

[@moritztabor1678]

😂😂😂

[@Pavlos_Charalambous]

And that's why you should never miss a leg day

[@JGCR59]

The one reason they actually did have to remove the gun was not so much to use it as a conventional gun but to access the engine as access to it was blocked by the gun. Which certainly didn't help maintenance

[@Wastelandman7000]

Badly needed laugh at the title. Thanks folks

Love the detail on this shit fam ! I like that kind of stuff

[@Tinyuvm]

I love how those early german SPGs look like Ork Vehicles from 40k 😂

[@holgernarrog962]

It was unnecessary primitive. Why not taking the gun from its wheels put it a bit deeper in the Panzer I chassis add an 8mm protective shield.

[@czwarty7878]

Because it was a stop-gap solution. Proper 15cm support vehicle was made and it was the Grille - this one was designed for it's role from ground up and doesn't exactly look "primitive".

[@holgernarrog962]

@@czwarty7878 The manufacturer of this interim solution was ALKETT. Alkett was an established producer of tank vehicles. On my point of view unnecessary primitive. The Grille was built on a 38T body. These vehicles were used for tank destroyers and other purposes. The Mark I tank was really surplus and as of 1941 of no use anymore.

[@PeterT-i1w]

the fact they didn't even bother to take off the WHEELS of the gun ...

Ferda!!!

Can you guys please do a video obaut the american t29 heavy? I cant seem to find any videos on it aside from warthunder reviews

[@Sd1v8v]

So 6 of them are still at the bottom of the Adriatic. Lots of tanks went down wylam in transit. May be a good idea for a article.

[@barnabyandanthonysofficial1497]

@2:05 look at that pogger lighting up his spliff between rounds

[@draconian6692]

I personally dont get why they didnt get a fast geared tracktor to just push the standard 15cm gun. It would have been cheaper and have better power to weight ratio than the pz1

[@JeanLucCaptain]

Alket puts a gun on a panzer chassis gives it a ludicrously long designation and calls it a day lol.

[@pacificostudios]

Did the 15 cm SIG 33 howitzer use semi-fixed ammunition like most 150 mm guns? The film doesn't show anyone putting powder bags in after the projectile. If so, that might explain why recoil didn't destroy the vehicle on the first shot.

[@old_guard2431]

Wikipedia article on the weapon indicates semi-fixed, without a lot of detail. Consider the source, but seems likely. Reference to the #6 charge indicates crews could vary propellant, and the ready ammunition seems to start out as a combined round, rather than separate shells/powder cases.

[@pacificostudios]

@@old_guard2431 - That makes sense. But you can imagine that crew would be careful before shooting a hot load from something so precarious.

[@RandomZFella]

Good design, wrong chassis
