But for most of Clan history they did not fight any Trial with anything approaching battle conditions. They fought until X amount of hits on armor, maybe hull breach or some other artificial condition designed to test skill of the CO while maintaining the hard to replace asset. The ONLY times they really fought as warships would have been during Op Klondike and it really did not come up again until the Jags faced the Second League . . . and then, did the Clans learn from what happened to Jaguars- and in one case Bear- warships? HIGHLY unlikely since, well its the Jags they are obvious failures since they let the Inner Sphere defeat them- besides who was present except maybe Falcons on Huntress to watch?
So yeah, the Ravens and other Clans would have Star League Defense Force FM 6-66, 'How to Warship' and know that they need so many drills a week/month/year to check the boxes . . . but a couple of things. First, the warriors in command of the ship, piloting/nav, tactical . . . are they really going to care about them outside of 'shooting' for due diligence? We have plenty of fluff bits of Star Colonels and Galaxy Commanders who advanced on their tactical prowess who were hopeless in leading let alone supporting their clusters- clueless at logistics, reading a strategic map, etc. "I do not care about anything but firing my Heavy NPPCs, do what you need to feel comfortable Tech Zec, but I want those HNPPCs firing when I press the big red button or you will be out the airlock!"
Second, are they going to try to keep the crews together to avoid constant transfers that hurt team cohesiveness? does the saKhan (who is in charge of the touman's operations) understand the need to transfer engineering department heads to spread around experience- do they even recognize (or have a deputy/staff) qualified personnel? especially when they are likely a Mechwarrior or Elemental, and most likely totally unfamiliar with warship operations?
Third, does any warrior officer or their technical subordinate have experience in say damage control, fighting ship fires in zero-g? MAYBE some in accidents, but during that time any knowledge of damage control operations has long since lapsed . . . all those pros from the Aramis wars were beached along with a lot of other Star League personnel. They died during the Exodus civil wars or were shuffled off by the proto-Clans and it appears the Ravens were the only ones who ended up with anyone who had a clue about ship operations. And the Clans really had no period where they really gained any warship combat experience- instead playing simulator battles or tag with weapon systems.
Finally, 'if he wanted his ship to survive a battle' assumes they have institutional knowledge . . . and a manual that is written with a shared history/viewpoint is not going to be completely understood by someone with a dramatically different view as the Clan culture would generate. The example I know best is look at the artillery topics, I am willing to bet some people scratch their heads over things that Charlie 6 & I have discussed as doctrine even when we have taken time to explain to laymen. Because from our personal history and viewpoint there are concepts we take for granted (think of any jargon you know as your job)- TOT, hip shoot, masking terrain, danger close, back blast, safety T, and others. He was a Marine and I was Army but we were both artillery and could discuss those concepts. If we had a Brit artilleryman, they would be able to drop into the conversation and understand even with the larger cultural background gap. Not sure if a Russian or Chinese military individual would get the jargon but they would understand the concepts. But if I were to talk to one of Ghengis mounted warriors, he would be clueless . . . heck, I could talk to a Navy ASW type and even though we both used NATO equipment they are not going to understand all the unspoken information.
So while the Clan warship commander may have a perfectly preserved set of manuals and even simulator programs in their warship memory banks, and they use a Star League built ship & equipment . . . they are not going to understand the underlying meaning in any of the material they inherited.
