Is Gao Guang dealing with personal matters?
No, Gao Guang is addressing issues shared by the Shooting Club. He's contributing to the group as a whole.
Behind the Shooting Club lies an even larger and loosely connected interest group. With Gao Guang stepping up to the frontlines, even if these people are unwilling to offer direct assistance, they at least turn a blind eye.
As for the immediate members of the Shooting Club, those with money provide money, those with strength contribute effort. No matter how difficult it might be, if there's a way to solve the problem, they go all-in without hesitation.
The Shadow Mercenary Corps are nominally a mercenary group, but in reality, they are part of the Phantom Brigade. Does Gao Guang now have the ability to quietly get a squad out of the United States? The answer is no.
