As a man, how could Gao Yuan not like guns? He did more than just like them, he was extremely passionate about them.
It's just that there wasn't much use for guns in daily combat, so Gao Yuan didn't carry one around all the time like other people, but that wasn't his preference.
Given the chance, Gao Yuan would have collected all his favorite guns, both rifles and pistols, all the famous guns of the world.
And this was a good opportunity, as here one could essentially sweep clean all the firearms revered by military enthusiasts.
The Americans had rifles like the HK416 and HK417; one could also see SCAR-L and SCAR-H, the latest HK433 recently adopted by the Germans, and the M4s still in use by Americans.
Even the L85A2, this peerless divine firearm, was present. Seeing that English soldier carrying the L85A2, Gao Yuan truly wondered whether this base was actually particularly well-stocked with weapons, otherwise, why wouldn't that English soldier swap his gun for another?
