Dynamite is a timed explosive built for wrecking vehicles rather than soldiers on foot. Throw it under an armored car or tank and get clear before the fuse runs out.
Lead a moving vehicle a little with your throw so the stick lands where it will be when the fuse ends. Against parked or slow vehicles, drop it right next to the wheels. Use frag grenades instead for soldiers on foot.
C4 gives you full control of the timing, which is safer on fast vehicles. Dynamite is simpler to use on the fly.
Bait
Bait is a chunk of meat you throw to draw predators to a spot. Toss it near FND soldiers and let the local wildlife do the fighting, or use it to bring out animals while hunting.
C4
C4 is a remote-detonated explosive you place and trigger when the moment is right. It is your best tool for setting traps on roads, wiping out parked vehicles or blowing up a target without being nearby.
EMP Grenade
The EMP Grenade shuts down vehicles, cameras and alarms in its blast. Throw one before you sneak into a base to blind its security, or stop a vehicle dead in its tracks.
Flash Grenade
The Flash Grenade blinds every enemy close to where it goes off. It buys you a few seconds to rush a room, escape or line up headshots while soldiers stumble around.
