Since Xlucine suggested it in the general AFV thread, here is a new version of the old Tank ID thread that used to exist at the WoT forums, back before the great exodus to SH.
The rules are simple. Post a picture of some sort of AFV and everyone has to try to name what it is. Try to avoid posting a new picture until the previous picture is identified. Generally, the person who was first to correctly ID the picture in question gets to post the next picture, unless they want to pass. If a picture is not ID'd in a day or two, the person that posted it should say what it is and bask in their own sense of superiority. They should then post a new picture for the sake of keeping the thread moving. Please, no fictional tanks, paper napkin drawings that never made it to prototype or pictures where the vehicle in question is obscured or particularly hard to see. Also, if posting a picture of an unusual variant of a relatively common vehicle, be sure to note that you are looking for the specific variant name, not just the general family of vehicles it belongs to (for example, if I post a picture of a Panzer IV with the hydrostat drive, I would say in the post something like "What makes this Panzer IV unusual?" since everyone can ID a Panzer IV)
It is perfectly ok to shame those that make spectacularly wrong guesses. That's just how we roll around here.
Some of you may have seen this pic recently on WT forum, in some thread arguing the protection of JGSDF Type 90:
Discussion on WT forum
To be straight, the Chinese annotation in the table said it is just a GUESSING.
This annotation could be totally nonsense but unfortunately a barrier between languages prevent you guys see throught it.
In fact, again, this document itself is about JGSDF Type 10 MBT, not Type 90.
Same trick, different people, huh?
JGSDF specification handbook of Type 10 MBT
page 59, Appendix B, performance (regulations) and data
Let's talk about these regulations and how they were made and encrypted.
You may know that Japanese have Hirakana and Katakana, like Latin have letters and capital letters.
As you can see, some of the most crucial numbers and descriptions are covered by a Hirakana or Katakana or Romaji(Latin letters).
These numbers and descriptions were collected and listed in some append book, called Bessatsu(別冊).
When you look up to the append book, just like viewing the answer sheet of an exam paper. But when numbers and descriptions were censored, you'll never know what it said.
For example, the frontal protection:
“耐弾性 - 正面 - 正面要部は、【あ】に射距離【え】m相当存速において、貫徹されない。”
耐弹性 - 正面 - 正面重要部位可抵御【あ】以相当于射击距离【え】米存速的射击，不会贯穿。
It read like this:
Protection - Frontal - Frontal crucial part should withstand 【あ】 firing at a distance of 【え】meter speed reduce equivalent, and not penetrate.
【あ】stands for certain type of ammunition, probably APFSDS, but don't know whether it is production shot or experimental.
【え】stands for certain firing distance, could be 1000 , 1500 or 2000 (meters), but on such a long distance, shot could be effect by wind and gravity, thus cannot aim on the protection area of target vehicle precisely.
The usual solution is to fire from a much closer range, from 200 to 550 meters, while reducing the propellant charge so that the end speed of AP shot could match the speed drop on certain distance. This is an equivalant method.
Some people argue that Type 90 MBT can withstand AP shot (JM33) firing from another Type 90 MBT, on a distance about 250 meters. The source of this statement came from an unknown video clip, which they have never seen. Firing on closer range is for better aim, and they could have use reduced charge to simulate a much longer range, but we cannot prove.
The Joburg war museum (now Ditsong museum of military history) is a bit of an odd beast. Located right next to the Joburg Zoo, it's sort of small and kind of schizo in terms of content. It's also partly a monument to the fallen, partly a conference/events venue and partly a warehouse for all the odds and ends that the country has collected over the years and isn't sure what to do with.
Anyway, I went there recently with my son and brought back tonnes of photos. These will be dumped around the forum in the appropriate places (tanks, planes, big guns and small arms), with this thread serving as an overview.
The entrance is like the rest of the place: tucked away a bit and kind of pokey.
A few metres away, though, is an impressive monument to the British dead from the second Boer war. Nothing screams 'empire' like crushing your enemies and then putting up a huge shrine to your own war dead in their former city.
The museum is divided into a few big halls, some narrow glass-fronted galleries, an open park area and a central conference venue. One thing which should be noted is that two of the galleries do not allow photography. The interior pictures from these halls posted below are merely accurate replicas made from memory and a bunch of 1:72 models I happened to have lying around.
Brink Hall from the front and back. It has a number of aircraft and related gear, as well as stuff related to the Boer war and First World War. The Brink Hall is pretty much the first thing you're going to wander into, as its close to the entrance.
Between the two halls is a little artillery display. From here you can either go right to the open park area or straight into the Adler Hall.
The Adler Hall from a few angles. This one is dedicated to small arms, uniforms, a POW exhibit and just about everything else you can cram into a small hall and still fit. It also has a few vehicles (M3 light, Sexton, M4) that are opened up and/or have stairs so that you can look into them.
Past the uniform exhibit (which snakes around the sides and back of the hall) is a rather random exhibit on Cuito and the Border war. The cut-up Ratel in there has a driver's station with a display above it. The display shows grainy footage from the battle on a loop.
Just past the artillery display thingy there are a few naval objects on display. The most interesting is probably this Nazi mini-sub which we got from who-knows-where. The placement of the sub did something strange to my phone camera, so there are no photos with it in perfectly focus.
Most of the outdoor park stuff is going into other posts, so I'm just putting this there. These are the only two things that kids are allowed to clamber all over in the museum, and the little tykes seem to have stripped them down to bare metal over the years in doing so. I actually have lots of photos of these, as my little one was very insistent on spending time driving the jeep/flying the plane.
All in all: a decent little museum, and home to a few interesting odds and ends that I'll put up in other places.
