A view of the treads. Thank to alert commenter Alex Sonny for pointing out that the front is a bit too long. I took this into account, redid the measurements, and realized that although the proportioning of the overall model is good, the distance between the front wheel and the first of the six lower wheels is too far, which makes the tank's front look too long.

The M55 was an American fully enclosed and armored self-propelled artillery based on the M53 155 mm assault gun. It had a 203.2 mm howitzer which could traverse 30░ left or right, carrying only 10 rounds of ammunition. The gun had a maximum range of 16,916 meters (10.51 miles) with a rate of fire of one round every two minutes. The M55 armor was light, 25 mm maximum, but sufficient to protect the crew from indirect artillery hits or small arms fire. (Source: World of Tanks wiki)
Brick Count: 2131
Building Guide Length: An Indeterminate Number (LDD refused to load it, so I'm assuming it's simply too big for LDD to do.)
In my last model (the M40) I said that tank was the largest I had ever built. This monster more than doubles the brick count of the M40, smashing apart my previous record (although this is mostly due to the nature of the treads, which I'll get to in a second.) The model has a large number of magically "floating" bricks, but that's only to make room for other stuff, and I'm fairly certain only exists in the front upper corners of the turret armor. The interior is probably the most detailed one I've ever done, although that's mostly because the bay doors on the rear had to be open and I didn't want the interior to be bland.
The treads are made with four rows of small treads, which probably account for roughly half, if not more, of the brick count. This was necessary, however, because the five-stud-wide tracks attached to the front armor would stick awkwardly out of the side and require me to widen the whole tank to make it look good, which would have screwed up the proportions of the model. However, I like how the four-wide tracks turned out.
The turret does not rotate; I forgot to make it do so until the last minute, at which point fixing it would have required rebuilding the entire turret, which I'd already done a few times to perfect the armor. I did remember to make the gun move up and down though!
oh, about those tracks... you know you can make custom sized track pieces in LDD by building them out of tiny lift arms, axles, and stops in the technic section... just make a track piece and clone the heck out of it.

Amazing model with such great detail!
Quoting Alex Sonny
Amazing! Very nice detail, on such a large scale! I just think the front is a bit too long, it has to look more like M44's front. Otherwise a perfect model!

Thanks everyone! Also, Alex, I noticed that too. I double checked the scale, and although the proportioning seems alright to me, the front wheel is too far from the first of the six lower wheels. Thanks for helping me catch that!
