Coincidentally, my son and I spent about 4 hours at our local Lego hobby shop this weekend. There is something soothing about building Legos.

I'll be interested to see the finished product of the tank if you post any pictures. We bought some knock-off SWAT and SEAL minifigures from Aliexpress a few years ago. They were fun to build with all the accessories (NVG, knife, etc).
