Corrected entry: Near the end of the film, Magneto & Mystique are approaching the guarded Cerebro machine. There are around 8 guards, but when Magneto pulls all the pins out of their grenades, and then collects them into a pile, there are around 30 pins.

Correction: High chance that the guards carried more than just one grenade each.
