It was the battle that effectively brought the war in Europe to an end, and its story has been told many times. Although everyone on all sides could see how it would end, fanatical Nazis continued to fight street by street, making the battle for Berlin into a horrific and blood-soaked finale to the terrible years of war. The Reichstag itself was of little importance since Hitler had no need of a parliament, and was an empty shell by 1945. Yet the building was strong and made a good strongpoint, and was of course a symbolic landmark that the Soviets were keen to raise their flag on as soon as possible. When the Reichstag fell on May 2nd it was not the end of the war, but the end would come a few days later.
As usual, we begin by considering the figures you get in this set. They are:
In addition, the set includes 1 sprue from Italeri's T34/85 (7515). The chosen figure sets are good ones, not without their problems, but correctly uniformed and equipped for the last days of the war. Many of the defenders of the Reichstag were SS troops, and would have had the weapons we see here. The defence of the Reichstag also included two of the 8.8 cm Flak, so the inclusion of that kit here is another plus point. Soviet tanks took part in the various assaults, so the T34 makes sense too. 
Of course the major piece here is the Reichstag model. This is of the front of the building, but while it is an impressive 68 cm wide it is much smaller than it would be if it copied the actual building (were it a completely accurate model of the front of the Reichstag it would be a whopping 1.3 metres wide). Nonetheless it is a complex model that does very well at representing this historic building, and for a playset it is plenty big enough to suggest the enormity of the strongpoint. The various architectural details are very well done, as is the level of damage, including the bricked-up windows done to make it easier to defend. This was the largest and most complex laser-cut MDF model Italeri had yet released in their battleset series, and a very fine model it is too. As a key objective for so important a battle it serves very well.
As always there are photos of a finished model, and as always this is greatly more complicated and detailed than the actual product can provide. The painting of the figures is great, and that of the battle-damaged Reichstag is particularly good. The modeller has provided a wealth of terrain and battle debris which is equally terrific but what you might call a 'serving suggestion' since none of it comes in the box (even a German tank, which you do not get). Good, inspirational stuff, but a naughty exaggeration of what's in the box.
Having said that, the diorama does show what can be achieved using this set as a starting point. The building is the star of the show, and since it is unusual to have battles around major public buildings, this set provides a really fascinating as well as a very unusual battle for a conflict that is still so familiar to us today.
