Gao Yang and his two companions each possessed the capability to independently complete a reconnaissance mission.
Gao Yang was a marksman, but if necessary, he could also lean towards the role of a sniper, an occupation that naturally involved covert reconnaissance. Although there might have been some discrepancies compared to full-time snipers, Gao Yang was capable of independently executing a sniping operation. The main area where he fell short compared to top-tier snipers was in the ability to remain concealed for long periods before delivering a fatal shot. However, in other aspects, there was hardly any difference.
Jansen claimed to be from a reconnaissance force background. His approach to scouting tended towards the use of technical methods, which differed from Gao Yang's traditional close-range reconnaissance, but they complemented each other well.
