How to reliably refill incendiary or other grenades? - African American Girl in Kerchief and Other Woman with Dreadlocks

When running challenging missions, or daily hard missions I tend to run out of grenades after 1-2 missions. I rely on stun or incendiary grenades for CC. I know only of the home base restock function that does not suffice.

Are there other functions in the game to quickly refill grenades, besides random drops, such as stun or incendiary that are not found in restock boxes?
