Since the acquisition of Sneak Attack technology from the rogue commander Prince Kassad, GLA forces often use this giant digging machine to ambush enemy bases.
However, several problems arises within the frequent-user veteran warriors. It's often the digging machine were aimed too high, resulting the tunnel exit become too steep, making their vehicles difficult to climb out. Frequent complaints also came that the gate door not sealed up completely when the digging process, thus a lot of sands and dirt fell into the tunnel corridors making the preparing squad vehicle often being stuck there.
Now the GLA engineers have corrected these errors and the Sneak Attack operators have been trained as well. The Sneak Attack tunnel exits now become less steep and sturdier than before, increasing the success rate of base ambushing operations.
Nice!
What does the GLA emblem on the door mean?
from the gathered evidences, different GLA emblems marks the company.
just like the US have ^ > V < markings on their vehicles.
my speculation:
this one, same with the one at GLA Barracks, seems the underground company, dealing with tunnels and troop recruitments.
the one at Arms Dealer (a crescent with a blade upward) meant for armored company.
and the other one, with two crossing crescents with a blade, at the Cargo Plane and GLA Hole is support division.
Or air force. Surprisingly nobody has used them for Generals emblems yet...
