Welcome to the forgotten tank channel. I'm your host. Tank Jesus .

Chieftain: we haven't quiet figure this out. Sweden: we are not done building it yet.

"We want a tank, and we want an armoured car." "Can't afford both." "How about one that is both?"

Chieftain: "German vehicles are overly complicated." Sweden: "Hold my Surströmming!"

Judging by WG standards, those wheels are the most effective spaced armor in the universe.

I showed my son this video. He wants to be an engineer. The expression of near horror on his face was precious to behold. I then explained Christie's system to him and that made him feel better because at least it worked. Well, long as it's not too heavy and etc... :D

From what I've read, it could switch between tracks and wheels in 30 seconds while on the move, which was unique and incredibly fast compared to other wheel-come-track designs.

Even though some of these non-sponsored Wargaming videos of vehicles that will never be added to the game they are still extremely interesting on the history of the vehicle, and how it works. Keep up the good content Chieftain

2:07 I don't know, I think it looks more like a puma

I always love it when people are confused to hear an engineering firm specializing in massive metal machines like locomotives and tanks has a carpentry team. Never occurs to them that you would want to make wooden copies of many metal components for testing or display purposes. Shows how little most people understand about how the stuff they use actually comes about, and partly why they don't appreciate manufacturing workers nearly as much as they should.

KZfaq asked me to rate this video and describe why gave it 5 stars. Of the 6 choices available I chose "heart warming" and "calming." 😁

More please ;). Surely there's enthusiastic and capable folks in Sweden (they build Viking ships from logs after all) that could embark on the adventure of restoring this unique vehicle, take out the engine and get it running while another team looks at the drive system. Sounds like the perfect winter project, something to do on those long winter evenings and it could all be documented through some cool doco that I'm sure would be popular on youtube. Perhaps Wargaming could fund it since they are no longer paying the Chieftain to fly around filming, exploring and explaining tanks.

If any tank could use a collaboration with Bovington to reverse engineer or dismantle in order to comprehend the processes at play this would be it. Fascinating! Thank you Nick.

"We think', "We cant figure it out". Who lost the manual? People, this is why you keep the manuals!

Looks like Swedish tracks were a major influence on the tracks on the Pz I, II, III and IV. Very similar, and the suspension looks much like the Pz I.

For non-Scandinavians, "stridsvogn" literally means "strife wagon". Personally, I like the Danish "kampvogn" which means "battle" or "match" wagon. Either way, I think they are way better than the English term "tank".

During the week it's a tank. On weekends you can load the kids, towels, rafts, and sandwiches, lower the wheels, and take it to the beach. The only thing missing is the BV.

If M.C. Escher had become a tank engineer, that is what you would get.

15:50 "tracked sistem that was CRAP" i laughed so hard...

Interesting and informative, as always. Thanks!

Oh I love this one, the tracks and wheels in the 1930s were such a novel concept, great video.

Thank you Chief for another great video. 😊😊

I want to pull it apart to reverse engineer it, if there are no surviving documents for the vehicle reverse engineering may be the only way to see how it works. For instance the steering wheel looks like it has a tilt forward mechanism that disconnects it from the steering shaft (allows the rear driver to use the steering without the wheel causing a hazard for the front driver) I love historic prototype oddities where engineers are clearly looking for innovative solutions for problems and they are not afraid to think outside the box

I hope there's a lot more stuff coming on with stefan and the chieftain, they're so great together!

7:00 looks in cab. thinks wow this is going to be complicated. stops vid gose and gets cup of tea. restarts vid. let the nut scratching commence. :)

Seems like having someone Stephan's size along when crawling through WWII era tanks would give a better representation of their ergonomics. Nothing against Chieftain but he's a giant by comparison as illustrated at 15:02.

Loving the patented pokey thing!

Really cool that so much of it's mechanical functioning is still undefined. It's like a treasure hunt!

"This is a Great Design, but it's NOT Complicated enough. Can you make it more Convoluted?" said NO ONE Ever. This looks like a decent design that someone just couldn't leave well enough alone.

Well with the tracks being that bad... good thing it has wheels to drive away with lol

the 2 leavers on both sides of the front drivers seat are diff locks for tight turning quite like you find in many tractors today.

I like those Swedish car guys but every time you're around them they just sit around tellin SAAB stories 😂🤣😂🤣😂🤠

11:20 - Suddenly the Chieftain throws us off the track so to speak by casually mentioning that it has a rear driver position. @le Chieftain - It's merchandise; not "merchanidse"; might want to correct that typo.

Nice video sir chieftain!!!

Find a woman who's as happy to see you as Nick is to see the Track Tensioning System

Bonkers complexity. But brilliant too. Let's see this approach on all MBT's going forward.

They really need to add this to War Thunder. You could use the same for Hull Aiming and allow the fm/31 to deploy it's wheels while in combat since it was capable of doing so in real life.

The lighting in the tank makes anyone sitting in it look like they have been green screened into the hatch.

It would be interesting to revisit. Some of the ideas in this

"Rather curved horns... Tusks? Call it the Warthog?" Nah, chuppa-thingy.

Awesome thanks

I see a new tier 8 premium tank :P

Until 20 minutes ago, I thought I could learn to drive anything with wheels. This franken-tank has completely crushed that complex,. After loss of my Superman complex in the Army, and now this one, what do I have left?

I'm rather impressed that the switch from track to wheel power and steering is that simple to operate for the driver.

Sooo, is it a tracked armored car, or a wheeled tank?

Oh and the term is 'traverse leaf spring', also used in Model T and Corvette.

I love the subtitles at the start "street swaggins"

The first example of weird Stridsvagn hydraulics.

Any one else love how strange this tank is . Hey like for the tusks

IKEA might have the instruction manual for the tank.

War Gaming: *Makes series to promote World of Tanks* War Thunder Fans: *crab rave*

As a swed. I Think Stefan has a very... very stearotypical swedish accent

I want to see that film footage he talked about of this vehicle running, that would be really interesting.

Sweet Moses!!! Clearly SOMEBODY did not subscribe to, or ever heard of, the principal of "Keep It Simple Stupid!".

Looks like the cab of an old London Transport bus. Just check to see if they have one of those things for showing which route it's on.

Reminds me vaguely about a towable double roller steamroller. They have a single set of wheels that can be lowered and the unit towed to a new site, rather than needing a trailer.

Modern tall style semi air bags. This could be KILLER. In low voltage light tank. Killer quiet. TANK. On air. Light weight tracks high speed

What a complicated & bizarre beast

Holy hell, was interested in getting a couple of the shirts from the Everpress shop, but that shipping cost is outrageous...

Hey Nicholas! Great vid! Ever Walked around an E4 M4A3 before?

Sudden urge to go sand and polish the treads on car tires. This could be the next up and coming mod..

Missing the rotor shaft for the helicopter blades and periscope for underwater operation.

Leave it to the Swedes to make the gun and mantlet out of wood. Probably compressed sawdust or wood chips too.

Interesting concept I fully understand the thinking. You could deploy on wheels and retract the wheels for cross country it eliminates the need for transport truck or rail. I am impressed with the engineering

Saw a manual for FM/31 at IKEA yesterday. Comes complete with elaborate drawings and instructions for this wheelacked fighting vehicle. There is a supplemental glacis armor kit available for an extra charge, but the instructions to attach it to the wooden glacis plate are also in the manual.

Interesting design. I wouldn't mind going there to see the m/40 linx armoured reconnaissance vehicle

This is bloody great! What is it? We don't know!

Ohhhh... A convertable tank..😮😮

The Swedish are known for innovative tanks and cars

This thing gave me a headache instantly.

I feel like ive seen this vechial before, only there was not talk of track tensioning, a mustache and a "they weren't vary good. But they built them anyways."

Fiberoptics could help explore beneath the engine, without removing the whole thing.

Im sure if we could get to sweden a group of fitters could strip the back down and and verify the different systems. Itd be a great holiday come exploring experience.

Looks a lot like the sdkfz 254 great story about the freedom tank needs to be told

"...The rather elaborate-looking, curved 'tusks'... call it the Warthog?" Nah, I'd say it's more like a puma.

you really should do a compilation of all your "tank is on fire" scenes

Nick, is the Chieftain still your favourite tank?

I wonder if the steering wheel/levers combo is similar to the older M113s having the control laterals and pivot steer brakes as separate controls.

this...looks interesting. i wonder if Minsk is interested in bringing it to WoT tho...

sweden had foun out the secret of wheels armor surprised that they good at blocking shells, so hence decided to mount it on for additional armor

This thing is really interesting. I'd imagine the wheels don't move too far down to make contact with the road but it would at least have to clear the tracks, what about tracks sagging and touching the road as you drive over hills and bumps? From the inside of the wheel view it looks like the drive is engaged by hubs that lock in place just like a 4x4 (manually or inside the vehicle I couldn't tell). How the hell does it turn on the wheels? There isn't much room between the wheels and the track to allow the wheel to turn much. I couldn't see any wear or damage on the inside of the wheel for evidence though. Braking one side would flat spot the tires, I suppose you could do that but it doesn't make much sense. Anyways, cool and complex. Thanks Chieftain and supporters!

"Call it a warthog"? Nah, looks more like a Puma to me

There was an even weirder track/wheel 'thing' made by IIRC Vickers that appears in a few old (1920's?) AFV demonstration field days. Looked like a gashapon toy. A single central track and one wheel each side, all on the ground at the same time - I can only guess that the sole crew member had to sit astride a metal box for the track to run inside of - and the single crew man stuck out the top beyond shoulder height like a 'Whack-a-Mole'.

Let me guess, the lead engineer for this nightmare next got a job working for Ferdinand Porsche in Germany?

Aquavit may have had something toi with this contraption

Maybe Xray the lowering mechanism to see how it works. there are mobile Xray Systems that can be used to test materials, one of those would be handy...

in tanks were there was a steering instead of control leavers did the steering wheel have a limit on how far the drver could to avoid accidental track brakage?

What a legend....if you stop posting your videos man the world would physically stop spinning. Needless to say you must keep us well fed fine sir. Now get into the tiger 2 real good and deep, then we must see is3, then t10.

As a totally non-tank expert, why not have the wheels permanently down? On ground suitable for wheels, they'd be in use but as soon as they sunk too far to work, the tracks would automatically be in contact with the ground.

This is so overcomplicated I fail to believe a German was not involved

Streeds- vang is a pretty good aproximation for Strv.

Ether the engine fan is mounted wrong way around, or, it draws air from the front and exhausts it out the back like a Daimler Ferret

I would assume that one of the levers must control the drive mode, and the tillers may simply have been left on the donor tank when they started tacking all the new bits all over it to create a prototype. That is assuming they know what they are talking about when they determined both do the same thing. I would have assumed the tillers control steering brake/clutches, and the steering wheel steers the front wheels in road mode. Seems like it ought to be easy enough to determine, really.

The turret from the front looks like a 7TP

The swedish guy there is so nice.

The BRDM 1and 2 was considered to be too complex to use the additional wheels in the 50s/60s Cant imagine how bad this was in the 30s

Sir, if you could find a way to do one one the early German WW2 tank Version of this type or style? Thank you in advance, even if you can not or unable to.

So obvious question, whats the advantage for long range transport over just loading the tank onto a train car or even a truck trailer? Even with the road wheels I can't imagine its low maintenance, easy on crew or good on fuel, and the truck probably only costs as much as the extra system, and can move a tank even when its broken (which frankly those road wheels easily can be when acting like a tank), or be busy with other logistics most of the time.

This is a pretty good example of this type of vehicle, so we decided to do a video on it. We have no idea how the hell this works.

I want one.
