My files for my Testbox to compare with yours, if you are having trouble
look to end for GetClassSelection. Needs to be in. Also have an example for custom class further down. No guarantees to work, just good to reference. this one is Expansion. There is little change for vanilla mpmission init.c.

---------CUSTOM CLASS information to compare to yours.
Experiment with any appropriate item for that position.
Also can add rifle to backpack(if you have a mod that packs have a weapon slot).
