If you would like to learn more about steel microstructures and phase changes, you should find an an actual textbook
Do you have any recommendations or authors? -

Why not just reinvent the Wilson/Ellis bonded steel plate? IE: pour high carbon steel between two lower-carbon steel plates and then hot roll the resulting sandwich?
Because I didn’t know that existed? -

Cuba, why you do this?
What turret is this? It looks a little too square to be a ZSU-57, but the size is about right. -

Marks on the left looks like splashes that you see after HEAT warhead explosion, but there are no other marks around.
Looks like the projectile came in at an angle, considering the gouging on one side. Could the projectile have been a 14.5mm or maybe a 20mm SLAP? -
Ah shit, I totally forgot to tell you all how my JPA armor from the previous competition was made: basically it is a pseudo lamination of a FHA plate (hardened as deep as possible) with an additional RHA plate, as thick as the backing layer of the FHA, placed onto the hardened side.
The process involves taking the FHA, and then hydraulically pressing it into a fresh, red hot RHA "box" (that is slightly convex) and holding it there until the RHA is able to weld (if not using hot welding). The hardened face being pressed into is suppose to be rough, to give more surface area for the outer box to bond. The box sides are suppose to be long enough to come close to the back of the FH plate, where the more ductile (and easily weldable) section is, and welded back there, entombing the FH section and creating an armor package. When mounting in a vehicle, the "box" RHA layer is suppose to be the farthest from the inside, so that it is the first layer struck in the package.
As an example, if I have a 100mm plate hardened 25mm through, there would be a 75mm "box" place on it's face, and would produce a full 175mm package (the side tabs that are welded to the rear of the plate do not have to be 75mm thick). I intended for this armor to be the base armor due to it being expensive and time consuming to make, but used as such would probably be exceptional at it's job due to it almost exclusively having to defeat damaged penetrators and disrupted HEAT jets.
Hope you guys are inspired by this in the next competition, might be useful for enhancing the armor protection of such a light vehicle.

More T-72s FTW, also the comments are great, glad i left that train wreck before it actually fell apart

cross posting this, because it is Russian tank, and it has the new T-72 UBKH, @LoooSeR's fAVoRitE!

Hmmm, “The tanks ammo is extremely large and heavy... and would probably break an autoloader”
1. And the proposed ammunition wouldn’t also break the backs of the poor SoaB(s) having to load this gun?
2. I’m just going to refer you to any ship with large caliber guns, which almost exclusively used loading assistance*, but most importantly, the 8 inch Mark 16 used on the Des Moines class, and the 6 inch Mark 16 on the Worcester.
*Warships also have a couple other problems that required machines like ammunition elevators and rammers, that the small scale of tanks don’t have to worry about. -

An 80,000 ton battleship proposal, meant to be the maximum size that could still use the Panama Canal.
this one in particular is my favorite out of all the 80,000 ton proposals because she is armed with sextuple, 16 inch turrets, for a broadside of 24 shells, or 3 times that of the Colorado class (or all 3 Colorado’s combined). Also has 18 inch belt armor and a claimed maximum speed of 25 knots.

Hmmmm, for them to gain experience points to upgrade their virtual tanks, they would have to play mostly the online multiplayer... which is certainly how real life warfare is fought...*has flashbacks to kamikaze Ju-87s and Uber flanking, spawn camping light tanks*

I know this says WoT and WT, but would this also include World of Warships (WoWs), since several people have posted about world of warplanes?

They’ve started to get below 3 hours in 100% Eternal runs
2 hours, 17 minutes for Doom 2016, as well

Another pretty good metal soundtrack, some of my favorites being “Inferno” (4:21), “Devil”, and “Phobos Anomaly”. Names and times of specific tracks are in the description of the video.
Also, some of Mick Gordon’s previous work:

I guess I’ll say it: it’s not as good as the 2016 soundtrack. None of the tracks really stand out to me, unlike the original’s “Rip and Tear” “Damnation” “BFG Division” or even the short “At Doom’s Gate”. A lot of the notes used also sound a little to electronic/synthetic, and the base is notably reduced. Also, this soundtrack starts with what could be considered ambiance music, unlike 2016’s opening being a short monologue and then directly into some of the best metal I’ve ever heard. -

Have you noticed that in the videos from the latest fighting unlike in the past the Houthis don't burn the machinery they capture but use it? In the past videos Houthis operated exclusively as scattered light infantry but since months ago they seem to operate as a mechanized force with limited support of BMPs, tanks, technicals or captured MRAPs and Humwees. Often moving in convoys and seemingly not afraid of Saudi air force.
Saudi AF is too busy bombing schools and hospitals to attack the Houthis -
Was about to ask the same question about size limit. Now, I do remember that Mowag made a 10x10 version of the Piranha once, might go with something like that.
There is only the 30mm auto cannon and the RRs? No larger auto cannons or artillery / field guns?

This isn't really true. For example, the 6x45mm SAW had greater penetration than 7.62 NATO, despite having about 2/3rds the energy at range.
I guess I should have specified that the bullets were of similar construction, and proportionally scaled to each other, but yes, bullet anatomy is just as important as its striking energy. -
Conversely, if you’re looking for something more empirical to base your judgments on, you can calculate the energy each bullet has within that range; more energy would imply more penetration for dealing with body armors and punching through make-shift fortifications like stone/concrete, though this is not always the case.

After getting some time to read through the article provided by @Militarysta (thank you), I can sorta see how they can pull it off: Manganese and Silicon are both great for making strong steel, manganese increasing the harden-ability of low carbon steels, and silicon also increasing the harden-ability, and having the added benefit of maintaining the harness after tempering.
http://navweaps.com/index_nathan/metalprpsept2009.php#Manganese
http://navweaps.com/index_nathan/metalprpsept2009.php#Silicon
The retention of the bainite is still a mystery to me, as tempering and annealing (as discussed in the article) would transform the bainite with the remaining austenite into a more stable structure (again, pearlite), though maybe the large amount of silicon present (1.56-1.61% by mass) is interfering?
I’m curious too see how this armor develops, if they can make the plates thicker, or if they can keep the quality control while making these plates on a full industrial level.
-
Huh, that’s weird, usually Bainite is undesired for armor or structural components due to excessive brittleness:
http://navweaps.com/index_nathan/metalprpsept2009.php#Bainite
pearlite being just as tough but less brittle (on average) and martensite also being less brittle, and even tougher. Unless they want the contents of the container to fall out after the first hit, like ERA or something similar, this doesn’t look like an advancement.

tl;dr, Shima has only 2x 12.7cm turrets in the style of a late war Kagero, as well as some other issues...
