Brett has a medium armada of 100+ ships. Most of these ships are low speed ships, ranging in speed from 38.5km/h to 45.5km/h. A more interesting stat is that he has an ironclad, which is nearly his fastest ship, his best hull, and his best cannons. It would seem that his power is too concentrated, however he also has two Frigates of slightly less stats.
Brett won't release his tactics to the public. However From my battles with him, I have noticed that he rudely sends ships that could defeat swarms of ships 3 times as large as what you are sending; complete overkill. He did mention at one point what he called an S&S mission, where he would attack one faster ship with several other ships of equal or greater strengh. This is a prime example of his blantent overkill.
Brett has no allies. Alot of people have offered on the forums to be his ally, most of them bragging about their "fully cannoned rafts". It is rumoured that Invictus12 is an ally of Brett, but no one knows for sure.
Brett stalks Aso mainly. He is very obsessive about the people he stalks, and seems to enjoy sinking people's ships more than stealing their items.
