What is frag grenade in Gun Bros and how to use it?

Question

While playing Gun Bros (Brother in Arms), I see a Bro Op update saying

"Kill 25 enemies using frag grenades without dying"

But I do not know where to get frag grenade?

Go to the exclamation mark on your controls and select the frag grenades, it's probably the 4th one from the left.
