Awww, it's just for fun. I've heard lots of things for Lee. INFJ, ISFJ, and ESFJ are the common ones. I have a theory that he's an INTJ, although INFJ sounds best of the ones that are usually proposed.I've elsewhere heard ISFJ for Lee. But I tend to think these historical typings are sort of pointless.
Lee definitely strikes me as an Ni user, just because his strategy focused around his trying to build an abstract "masterplan" instead of just trying to put his army in favorable positions and then trusting them to win the fight, as was traditionally done at the time. INFJ is a definite possibility.I've heard INTJ for Grant (I can buy it from my readings about him), ESTP for Sherman (seems very likely from my research), ISFJ for Lee (he had the famous politeness anyhow), and I would guess some inferior Se type for Jackson maybe (his super weird physical eccentricities).
I've also seen Lee typed as ISFJ, but I agree with you (he seems very Ni). maybe 9w8 Sp/Sx?North-
