Not a single TactiCool School I know of teaches you for this eventuality:

Resident Eduardo Monteagudo said he witnessed the attack. “He was cooking and the monkey got on his shoulder and when he saw it, he tried to hit it and it bit him on the ear,” he said

The attacker eventually surrendered to authorities and will face a Florida Wildlife Monkey Judge. OK I don’t know if we have one of those but the way things work in Florida, I wouldn’t be surprised.

So, what do you use for a Home Invasion by monkey? I’d say shotgun with #6 for close range work.
