The MB-01 Eagle Command Base is the HQ of the Mars Mission Organization.
The Eagle Command Base was made in 2027. It came under constant Crystalien attack early in the war, and remained so. In 2027, the Alien Mothership landed nearby and created a base to attack it. However, with the use of the EM Pulse Cannon, it was destroyed.
After this incident, it carried on being a base of operations for the mining operation.
