According to the wiki, the Dutch Dozen are "a small, yet powerful group of mercenaries specialized in jungle warfare. It's members are trained to fight with low tech weapons and equipment, learning special survival techniques and how to conduct guerrilla warfare. They employ very older or outdated weapons such as the MAR-40, however, they are extremely well trained to use these weapons, often better than any marine with a M41A."
And their purpose in the game is "Should the Dutch's Team encounter a humanoid-ailen figure in the ship or elsewhere, they're to hunt it down at all costs. Otherwise they will assist on the defense of USS Almayer as usual." So, basically, it's an ERT that took inspiration from Major Dutch at the Predator incident that led to the creation of this team, which main purpose is to hunt and take down (above everything else) the predator(s) that spawn in the current round.
It's been a long time since Dutch Dozen spawned in the game and I think it's a wasted potential. Why? because it's the only ERT that has a special objective that is to deal with a special-almost event level role that is the Predator. I feel this role needs some love and re-structuration, like making the team available when the "Hunt" is active in the current round. Since actually predators are in a 'grey area' since they can easily fuck up the round for the normal marine/xeno players why don't give them a distraction? by picking 5-8 late joiners to spawn as Dutch Dozen in the almayer (or in a remote place of the map) and their job is to hunt down the predator and collect it's body meanwhile the predator tries to continue it's hunt; the honor code would put any member of the Dozen as worthy prey since they're humans trained to kill yautjas.
This ain't a suggestion but a debate, same goes to other discontinued ERT that we had some time ago.
