I think a lot turns on the term "mental map".
If by "mental map", we imagine the actual brain architecture and neural signaling of SLDF admirals getting copied and simulated in electronic form, then the CASPAR drones were arguably intelligent in a human-like way, i.e., they had strong artificial intelligence (AI), also known as artificial general intelligence (AGI). This is true scifi in the 2001/Star Wars droids/Blade Runner/Terminator/Star Trek TNG Data/Matrix/AI/I Robot/Ex Machina/Chappie vein. Even today we really have no idea how or why cognition, sapience, or consciousness emerges in human and other animal brains, nevertheless how to recreate it artificially.
If by "mental map", we mean that the decision making processes of SLDF admirals were written down and expressed in terms of computer software, then the CASPAR drones only had weak AI, which is really just massive data processing and pattern recognition that can or cannot be hooked up to value preferences and a decision tree. Weak AI is emerging in spades today, in everything from voice recognition software to driverless cars to grandmaster-beating chess computers. But it is very narrow (can only do one thing), and it does not imply cognition, sapience, or consciousness (Siri understands your voice but not your train of thought).
[The term "mental map" as actually used today involves neither of these definitions, FWIW.]
Although the differences between weak and strong AI existed back in the 1980s and 1990s when the CASPARs were first written up, those differences were probably not as well appreciated back then as they are today with the emergence of weak AI systems in the real world.
Given that BattleTech is supposed to be an extension of 1980s technology, I would stick with the weakest weak AI when describing the CASPARs. It should be little more than a lot of ship data getting reduced to some key variables running a kajillion quick simulations, the best of which is picked using a value matrix and decision tree based on how a bunch of SLDF admirals reacted under similar conditions in a bunch of war games. Yeah, it's hooked up to fusion drives and naval-grade weapons and has tons of safeguards, but at its heart, a CASPAR drone should be little more than a muscular version of IBM's Deep Blue supercomputer when it beat Gary Kasparov back in 1996. Deep Blue ran on specialized VLSI chips, while today's weak AI processing typically runs on gaming GPUs.
My 2 cents... YMMV.
