Inside the Chieftain's Hatch: Super Kurassier, Pt 2.

The SK-105 is an Austrian vehicle using the French-style oscillating turret. The design supposedly came with a number of drawbacks, such as stabilisation problems (Stabilising a multi-ton turret instead of just a gun) and NBC problems. However, Austrian engineers had a crack at these problems, creating this prototype vehicle. Here's part 2, the gunner and commander

Austria, a small nation, certainly got bang for their buck in terms of development with this particular tank. They tried out a bunch of ideas, to see what was worth developing in future tanks. I'm guessing they learned a lot. Plus it seems a serviceable tank in its own right for the era, despite its problems. Worst seems the gunner's position. Thanks Chieftain

Now I don't know if the problems caused by the tilting of the top of the turret for the crew are suspected by the Chieftain or if this is a fact reported by the crews. I don't have any information on this, but as far as I can see the crew is sitting very close to the pivot point, so the real movement in this area should be very small. So maybe this is a theoretical problem.

When I was editing, I checked with Franz because I was suspicious that I hadn't misinterpreted the situation and wanted to avoid an embarrassing error.

[@fulgrimventris8506]

most ERA (Especially the types designed to interfere with kinetic projectiles) requires a certain thickness of armor behind it, otherwise you'd just blow a hole in your own tank. the 2s25 is designed to be both amphibious and air mobile (Meaning that you can deploy it from a cargo plane on parachutes). Adding extra weight with ERA, or automation systems for the turret like you suggest, would compromise both of those abilities. Also, seating three crew in the hull of the 2s25 would not be possible, as the space to the left and right of the driver is taken up by fuel tanks.

Why is the switch gear in this Austrian AFV labelled in English, not German? I suspect it’s because they stole/borrowed/bought so much of it from US vehicles.

[@nirfz]

Probably because the fire control stuff was out of a Leo? But this question made me think... I wasn't a tanker, i was in AAA and i can't remember the lables of the AA gun and radar system. Or which language they were in. We bought the AAA system from swiss manufacturer Oerlikon, but they sold it worldwide (the same AA gun i was trained on is what the argentinians managed to shoot down a Harrier in the Falkands war and damage another one. None of their aircraft managed to do that) With the usually low numbers of things austria bought and buys, my guess would be, the numbers are too low to get our own lableing made. So we most likely get what the majority of customers buy. Also, basically the lable language doesn't matter as you get trained on it anyways. You get trained to find and use any button, lever etc. wihtout looking and under stress, so the lables could be in chinese or windings. (I mean we got drilled into where in our lockers which item of clothing and equipment had to be so if there's alarm, and the base gets blacked out, you could pack your pack wihtout any light and know where everything was.)

@@nirfz thanks for responding. I suppose the switchgear stuck out to me, because it didn’t fit with the expectations I got from flying. In your cockpit, the gauges are probably going to be labelled in one of the official languages of your country. I assumed the same was true for the foot sloggers.

(for the parts in dispute with hungary after WW1 that decided to stay with austria in a plebiscite in 1919) But i was quite surprised 20 years ago when i had to "check in" to the "hospital for accidents" in vienna when there were forms to fill out in: german, slovene, croatian, czech, slovak, hungarian, turkish, and a frew languages i wasn't able to decipher as quickly what they were.
