It began around 5 years ago as a hobby, then it really took off when I started doing research for WWII Online. Now I work at the Aberdeen Proving Grounds and have all sorts of access to information. The best parts of my site (in my opinion) are the interviews, the new movies, and the database tools. For the longest time I tried to find a website that let you compare units side-by-side and couldn't find one, so I made one myself.
I make no assertions that the data I have on my site is 100% correct (I think to do so is niave and foolish), so if you find any mistakes and can give me better data - with credible sources - I'd be willing to make changes.
Anyway, I hope you enjoy the site.
