How to reliably refill incendiary or other grenades?

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?

In your base of operations you can get them for free from the Rewards Claim Vendor. He's in the back behind the stairs to Tech Wing.
