Sorry if off-topic but I guess this would be interesting for you. 
 
I have just finished reading the chronicle of Czechoslovak tank brigade in USSR and since this was the only our tank unit on the eastern front (and the first unit to reach today's Czech Republic territory) and a relatively small unit, it's pretty well documented and researched day by day, name after name, tank after tank. I'm giving here some confirmed numbers from Ostrava operation which was in a way comparable to Berlin thrust. The battle was fought in the same time (but it took twice longer and even fighting for Opava/Troppau city took longer than for Berlin proper), it was fought for the last industrial area of the Third Reich (80% of industry by March 1945) and against up to 50 km deep defence lines (prepared by Heinrici) strenghtened by Czechoslovak pre-war fortifications (even though the Germans removed most of the weapons, cupolas etc. for Atlantic wall in previous years the objects were still literally immune to any field artillery weapons and some kept fighting till the end of war). The defenders had 25 divisions including 4 tank ones (8th, 16th, 17th, 19th, of course few on full strength by that time) while the attackers had very few tanks because of Berlin. The defence was also strenghtened by a lot of rivers, dense network of towns and villages and muddy spring soil. At the beginning of the second phase (the first phase happened farther to the east without success and without our tank brigade) there were only 63 Czechoslovak T-34 (10 of them T-34/76), 21 Soviet T-34 and 10 Soviet Su-76M. The Germans had 84 Panthers and a lot of other AFVs. Later Soviets added two batallions with 40 IS-2 obr.1944 and several other AFV units. For most of the fighting the Czechoslovak brigade was spearheading the attack in direction of Ostrava city (except for the first phase).  
 
Now the stats. In 38 days of active fighting in the operation the Czechoslovak brigade lost 52 tanks written off (43 T-34/85 and 9 T-34/76), basically all were damaged at some point but they kept returning in service over and over again because the unit kept advancing all the time. The manpower losses including tank riders were 148 dead and roughly 300 wounded. Tanks were usually lost to Panzerfausts in urban areas or in ambushes by tank destroyers and tanks in prepared camouflaged positions. Rather small number was destroyed by AT artillery or 88 mm Flak which is probably due to an extensive use of surprising directions of attack, use of speed and smokescreen (by artillery) which sometimes led to the capture of settlements before the defenders could get back to their weapons after the artillery barage. Also very few losses came from German counter attacks. Four tank commanders were killed by snipers. 
 
The confirmed German material losses by the Czechoslovak brigade are 24 tanks (mainly Panthers and some Pz.IV), 23 SPG (StuG.III, Jagdpanzer IV/L70, Jagdpanzer 38(t), Marder III and even one rare Jagdpanzer IV/70(a)), 17 Sd.Kfz.251 and 64 guns (including 15 Pak and 3 bateries of 88 mm Flak). Another at least two tanks (one Pz.IV, one Panther) and seven Sd.Kfz.251 were captured (also one Kettenkrad and other vehicles). The Pz.IV was later used by the brigade, the Panther not. Manpower losses are only estimated but they were very high because only the number of captured was in high hundreds while in a single engagement the number of POWs was usually lesser than number of the dead, there were quite many cases when units of SS fought to the last man. For exmaple in a fight for Štítina village there were 130 dead German bodies but only 2 captured (the combined Soviet/Czechoslovak losses in the same village were also over 100 dead).   
 
All data including photographs of a large portion of the destroyed German AFVs in the battle can be found in a book ISBN 80-86524-00-0.
 
P.S. About aircraft. In the entire history of the unit since 1943 to 1945 no tank was destroyed by an aircraft, only one was immobilised for a day.

I'm not sure if strong conclusions can be taken from that one video.  Different ammo types produce radically different amounts of recoil.  Discarding sabot training ammo doesn't produce too much recoil, while HE-FRAG is firing a big, heavy shell with a lot more momentum.
 
Aside from that, it occurs to me that the 120mm armed tanks listed are all heavier than the 125mm armed ones, although the weight of the K2 and T-14 overlap.
 
How a tank responds to the recoil of its gun firing is a function of the total momentum of the shot, the mass of the vehicle, the moment of inertia about the recoil axis (which is affected by which way the turret is facing), suspension stiffness, suspension damping, and recoil system length and forces.  You are correct in thinking that the stabilizer doesn't have very much to do with it.  In addition, I suspect that the K2 may enjoy very low recoil when firing from a stationary position, as it has adjustable suspension.  The rear hydropneumatic stations can be filled with additional gas pressure, which increases the K* of the stations, which reduces the amount that the tank rocks when firing provided the gun is pointed more or less forward.
 
The most effective way for light vehicles to deal with high trunnion loads from their cannons is to have very long recoil lengths for their cannons' recoil systems, but this comes at a cost.  The longer the recoil path of the cannon, the more empty space needs to be reserved to accommodate the movement of the breech.  This makes the turret more voluminous and taller.

I don't think that it's a significant cost driver.

The tube should be the snorkel for the engine exhaust.  The trapezoidal object is the snorkel adapter to fit over the engine intake.
