This role is how I interpreted their purpose as well. These tasks can be taken from SAS, SEALs, Rangers or LRSD.

When I think of Shock Troops, as suggested to [@POOHEAD189] I think more of the role of US Marines or Royal Marines. They are the breaching element attacking ahead of the rest of the unit. These Mandalorians are wearing a heavy armor unlike their Rebel Alliance counterparts in the other two platoons.

This is exactly what I was thinking.
