The Hand Grenade is a gadget featured in Battlefield Play4Free for every kit. It can be obtained using points in the tier 1 equipment expertise Frag Grenade training option. Its explosion range is about 5 meters; higher levels of the Frag grenade training option increase the number of grenades carried and their damage against vehicles.
Unlike in some first-person shooters, frag grenades cannot be cooked and are instead thrown when a player uses them in a noticeable arc. With a throwing range of around 50 meters and a blast radius of about 5 meters, frag grenades pose a great threat to infantry and light vehicles such as the FAV or HMMWV and their occupants. Grenades can even destroy heavy armor if a player is lucky.
Early on, a player should invest at least one training point into frag grenades as they can be uses to assault flags or soften up infantry targets. However, they should not be used to charge in to battle with as an enemy will kill the thrower or dodge the explosion if they see the grenade coming, making them best for retreating or just before contact.
They can also be used in conjunction with smoke grenades to kill anyone unfortunate to be caught in the smoke when assaulting a control point. Further increases in rank increase the number of grenades a soldier carries per life and increases the damage done to vehicles by grenades. Also, after buying all the four levels in the Frag grenade training option one can also purchase Dead Man's Trigger to drop a live grenade with a smaller blast radius, when the player dies.
