Kind of odd to have use a SMG in a border patrol exercise, unless they will travel into tight/urban areas.
The SMG is the squad’s ‘silenced’ weapon, having it is far less odd than the shotgun, which would only be useful at close range.
We need to remember that these guys are responsible for stopping the likes of IS and Al-Q infiltrating into Chinese territory, so it makes perfect sense for them to be equipped for serious combat ops against organised opponents.
Having a silenced weapons option to quietly take out enemy sentries to allow the squad to get the drop on them is a very useful capability to have.
As I said, the shotgun is the really odd choose. Maybe they carry it to fire shotgun taser rounds as a non-lethal ranged option against unarmed trespassers who resist without having to shoot them with live ammo?
