now that's something that I need in my back yard.
 
I don't think that picture is from WWII it could be later maybe the Hungarian uprising.
The front of the hull is distinct. Check out this site.

There are two tanks known as IS-3: Objekt 244 was an IS-2 rearmed with the long-barrelled 85mm cannon (D-5T-85-BM) and developed by LKZ (in Leningrad), which was never series-produced for service use.

Object 703 was developed in late 1944 by ChTZ (in Chelyabinsk) and left the factory shop in May 1945.[21] This tank had an improved armour layout, and a semi-hemispherical cast turret (resembling an upturned soup bowl) which became the hallmark of post-war Soviet tanks. While this low, hemispherical turret improved protection, it also significantly diminished the headroom, especially for the loader. The low turret also limited the maximum depression of the main gun, since the gun breech had little room inside the turret to elevate, and this limited the extent to which the IS-3 could take advantage of hull-down positions compared to higher Western tanks

The IS-3's pointed prow earned it the nickname Shchuka (Pike) by its crews. It weighed slightly less and stood 30 centimetres (12 in) lower than previous versions. Wartime production resulted in many mechanical problems and a hull weldline that had a tendency to crack open.[23]

The IS-3 came too late to see action in World War II. The first public demonstration of the IS-3 came on 7 September 1945 during the Allied victory parade on Charlottenburger Straße in Berlin, with the heavily reinforced 71st Guards Heavy Tank Regiment of the 2nd Guards Tank Army.[21] Starting in 1960, the IS-3 was slightly modernized as the IS-3M, in a manner similar to the IS-2M.
 
Caseless! VERY interesting!

This from Wikipedia:

300px-Ho-301_40_mm_projectile.jpg


The caseless design revolved around a specially designed projectile that was in effect a small rocket. The round used an internal propellant chamber at the rear of the projectile containing a ten gram silk bag filled with smokeless powder. Drilled into the base plate of the round are twelve 3.8 millimeter diameter exhaust holes. The propellant chamber is sealed by a thin aluminum sealing cup, which covers the exhaust holes. When the primer is struck, the bag of propellant ignites, and the pressure rises until the aluminum cup bursts, allowing the exhaust gas to rush through the exhaust holes pushing the projectile forward. The propellant was exhausted before the projectile left the barrel.

Because of the low muzzle velocity (245 meters/second or about 804 ft/sec - equivalent to a moderately powerful air rifle)[1] the weapon was only suited to attacking bombers; even here the extremely low muzzle velocity made it difficult to achieve hits from any position besides directly astern the target aircraft and well within the range of defensive counterfire.

I actually remember being part of some of this. NATO exercise Reforger 198?

I was part of perimeter security. It was impressive for me as a teen to see planes come in so fast that one was taxing at the end, the other slowing down in the middle and third touching down.
As a 19 year old I had never seen anything like it.

There are quite a few stretches of Autobahn which were specifically designed for this.

Oh! What seems to be the problem, Darling?

Cumulonimbus

If updrafts become stronger, those seemingly innocuous cumulus clouds may grow taller into what we call cumulonimbus clouds. These are the awe-inspiring and ominous clouds mainly observed during the summer months and can be indicative of developing thunderstorms, including lightning, hail, heavy rain and even tornadoes. The strongest thunderstorms can even produce cumulonimbus clouds that tower up to 60,000 feet!
