We are pretty close together with regards to 15k dTon battle riders. My costs more credits to keep deployed, but has armored bulkheads to reduce criticals on a bunch of systems, a small Marine contingent, two small-craft, a 'Breakaway Hull' to interface with the Tender, and a biosphere to keep the crew fed.
In particular, I wish 'Screens' were not so amazingly useless in the current edition.
