Does that mean they would act as mercs in exchange for drilling rights from Guyana? I would love to see Brazil's army unleashed on Maduro, but admit I am not up on Brazilian military's strength.
What Brazil claims is a active force of 213k troops and maybe a million in reserves.
I’d give them plus-grades on helicopter support, and they do have a special operations command (mostly known for anti-drug operations). They have over 400 M-60 tanks, although the value in this jungle setting would be a question-mark.
They have spent some money and maintained an appearance. I don’t think Venezuela can say that for their military. On Brazil’s appearance....I doubt if you can find anyone who denies they have a pretty corrupted political and industrial complex. It would be ill-advised for the US to pick sides on this matter.
