Welp, for generics, I've got some IS Standard, some longinus and achileus (bought from mercs I presume), and tornado and kobold (probably ditto).
Amazon is currently out of stock.
Spectre has no sculpt.
Between this stuff (a possible future purchase of an Amazon), and the marauder ba, I should be covered for most eras up to 31xx.
(I figured if it's on the mercs RAT, then most people will probably have access, either themselves anyway, or by purchasing from mercs/merc markets, right? (Theft is also an option)).
Mobility is good (most of them), ditto swarm attacks and battle claws (Some have those according to Sarna, yes?), and the longinus is good for defensive work, right? (I made purchases on the grounds of 1 BA model = 1 BA squad for the sake of scale).
