Thanks to Israel for the link!
Great vid but it does highlight an issue for the Brazilian Army. They're gonna have to modernize their heavy tanks or get new ones. I'm a bit surprised that they didn't get a piece of the German fire sale on Leopard 2's but they still have time for that. Of course the other option is to buy a few M1A1's that the US has in storage but I kinda doubt they'll go that way.
For better or worse when it comes to armor, the Brazilians go European.
Regardless they're gonna have to make a move soon. Too many of their neighbors and competitors have modern MBTs and they're going to have to keep pace.
