255 grenades:
Change your weapon to the grenades and hold Z until the throw meter is filled. 
When the grenade is being thrown, hold Z again until the meter is full. Repeat 
until you are on the last grenade. When it is thrown, you will have 255 
grenades. Note: This trick can be done with regular or flashbang grenades.

Disable flashbang effect:
Use the nightvision goggles after getting hit with a flashbang grenade to 
quickly restore your sight.
