Awesome set for display!

I admit it was tedious to build, but the final result was worth it. I really enjoy the design and the lego nazis that came with. (I'm also pretty sure one of them is Hitler, which is even better).

WOW but theres one problum

ok so im a kid that likes war and i was looking for this but there is one problum thats a lot of money now i know this is a lot of lego for a company to buy and i fully understand but i really want this and i have a shelf for all the lego sets that ive got from the past years and i love lego so to have that thing at the top that will look pretty cool so i love the product but im kinda scared to buy this thing because i think there will be a missing pice or a missing bag and i dont want that to happen so if theres a sale going on im hopeing my paraents will buy it for me.

Different set.

Hello, I haven't exactly bought the set, but I was thinking if you could add a separate set that is part of this set? Something like a train to pull the artillery cannon,

Bigger as a freaking Truck!!!!

So upon receiving the box I was thinking "no way can 4000 pieces fit in this box". Well they did, bag after bag of legos sprawled out over my 6-foot table. This set took me a sold 4 days of at least 30 hours if not more but it was so worth it. You can tell the pieces aren't of the highest quality, so for the smaller pieces, be gentle and for the big pieces, you really have to push to get the legos together. Upon completion I am still in awe of not only how freaking awesome this thing is, but how massive it is. 100% recommend, and definitely gonna buy more sets.
