User blog comment:P.F.U.C./Easy way to rank up wimps/@comment-3023564-20141014031310/@comment-11090687-20141014065530

MG Turrets are indeed a very good ranking partner. Or instead of planes, LCT's because they can kill critters very easily and also have some use when ranked up.

I simply used as much LCT's on the front row as I could fit and 1 Wimp on the second row firing once every battle to get full SP (divided by 2 of course).

Also just put your Wimps in every encounter you fight. Even if it's bound to die, it will still get some SP.
