I'd probably do it with the italian or swigger M24 chaffee (those are rank3)
But the dealbrakers for me are:
>3 (while it could be easy with long lancers torps on japanese destroyers, these are 2 naval shit challenges in a single bp)
>4 (i only play high tier ARB, and it's too fucking RNG to go and find specific vehicles for a fucking challenge
>5 (i don't play GRB, and if i do, i don't play CAS)
>BP3 (while in low tier it's easy to get this one, just playing the meta to terrorize seals and get it done is just retarded for me)
