No, you will not be blowing anything up but if you are not comfortable with your golf skills or are just looking to gain an advantage you may purchase a grenade.  You will only be able to purchase three grenades, and each will run you $10.00, but pick up your ball and lob it where you want it to land while yelling “GRENADE” – YES! You must yell GRENADE as you lob your golf ball and then continue the hole from there (yes the lob counts as a stroke).  Only one grenade may be used per hole.
