I build exclusively 1/72 scale armor, with the occasional 1/76 scale piece now and then. I have been building them for more than 30 years so I have amassed a collection numbering over 650 finished armor models. I've built Dragon, Trumpeter, RevellAG, Italeri, ESCI, RPM, Roden, ACE, UM Models, Military Wheels, Matchbox and Airfix among others. I usually finish between 40 and 45 1/72 scale armor models each year.
If you'd like to see my collection as of two years ago, check out my Webshots page. I have a load of photos there that show my 1/72 scale armor individually, and an album showing every model grouped by country. In that album, I warn you the photos are very huge! I did that on purpose so people could distinguish which vehicle is what as well as see some measure of detail. If you want to view them, click on the photo, then click on the little magnuifying glass icon to bring it up, then click on the photo again to see it full size. You'll know it's full sixed when you have to do a lot of scrolling up and down and back and forth.
Enough jabber, here's my Webshots page:

Enjoy.
