These videos have become my new entertainment.
Basically they show what a shit show it is policing in a mega-urban shit hole.
Lot of good FAL and FNC action, lot of "recon by gunfire" and "suppressive fire" and some pretty good (and bad peels and leapfrogging).
Also funny to watch the locals just stroll right down the center of the street while a full blown gun battle is taking place.
I always cringe when they roll the armored "beast" down a narrow blind alley that ends up being blocked, one IED and they're fucked.
It's all in Portuguese but it's pretty self explanatory.
