Kalran: Tales of the four nations/Master crawler

With how small the ADF forces are they don't need large forward bases. Instead using a small communications tower.

The tower contains advanced communication systems to call in ADF units to the field and requisition upgrades and protocols. It can also transport squad on the field into their dropship, which hovers in the stratosphere, where their forces can be relocated to another part of the battle through drop pods With advance defenses that can ward off almost anything and a redundant system built in so that the tower needs to be destroyed twice.

But with all of it's expensive technology and equipment the loss of a tower will force the ADF to cut their losses and retreat.

Due to the tower holding its units they will be separated into their own branches.
