Attrition Warfare Specialists

After the 27th Assimilators Warfleet took over a planet, they quickly began to build up their 'army'.

Swarms of nanomachines flew out of the starships, which happened to consist almost entirely of smart metal themselves.

This had many implications. One of them was that the starships could dynamically alter in shape and acquire new functions as needed.

The Assimilators made good use of this function by merging several 'starships' in orbital space stations and landbound complexes.

These facilities quickly turned into productive powerhouses. They centralized a lot of heavy industrial processes, thereby enabling them to obtain manufactured goods at reduced prices.

The expansion continued even after the Assimilators completely mastered the remote planet.

Instead of consolidating their control over this corner of space, the Assimilators chose to go aggressive.
