Mountain Eagle merely speculates on the intentions of those people, but their actions and equipment make him highly suspicious...
Brown Bear Camp has a helicopter, and if the Huai'en Tribe or the herders left at the Valley Laboratory suffer injuries due to drone attacks, the camp will likely dispatch a helicopter for rescue. At that point, they only need to be positioned correctly to shoot down the helicopter with a portable anti-aircraft missile.
The enemy's weapons are advanced enough to cause damage to Brown Bear Camp without requiring many personnel, making Mountain Eagle exceptionally wary!
He's not particularly worried about this team of identified enemies; he's concerned about whether there are other undiscovered enemies around.
The Huai'en Tribe has the closest relationship with Brown Bear Camp, but as the core of the region, other tribes facing problems will similarly seek aid from the camp.
