No, they learn that either from dirty cops, crooked professional military paid by the kingpins to work as instructors, or, as military service is still mandatory in Brazil, the young drug dealers enlist themselves in the army to learn the advanced techniques required for their “jobs”.

Believe me man, envious is the last thing you should be.

I am Brazilian, writing from Rio. They indeed receive training from dirty military men. When these young drug dealers turn 18, they try to enlist to learn how to use the heavy weapons that will ultimately become their working tools when they return to the slums.
