Oh, sorry, SM would be user @scattered mind If you don't recognize any of the others, just ask.
I won't actually kill off the units that I'm not using, but I plan on using them as little as possible (outside of Matthew/Legault for chests/doors as outlined in the OP; Serra will probably get some healing in before Priscilla/Skyleaf shows up, too) to focus EXP gains on those who are permanent team members. Their roles in the plot will be minimized as well, to give more attention to our chosen units.
