There seems to be some quaintness about the years in which the various Merkava tanks were introduced.
2294: MUL Names list 1.66 lists the standard version, TRO3075 and XTRO:Primitives 1 mention the Mk.II.
2325: MUL mentions the Mk.II.
2384: XTRO says the Mk.VI was introduces, but since it has LRMs, it seems unlikely since TechManual says that LRMs were introduced in 2400.
The questions would be:
1: So is the variant from 2294 the Mk.II? (seeing as the MUL is currently non-canon, it'd seem so).
2: Does the variant from 2325 even exist? (2b:) And if so, which Mk. would it be?
3: Is the introduction year on the Mk.VI correct, giving the LRM's introduction date?
