The Flashbang is a military stun grenade you buy at camps from Trust level 2. It blinds and stuns enemies so you can get away or line up kills. It is cheap and handy against human ambushes.
Throw one into a group of humans to stop return fire, then push in. It also buys time to escape a pack. It does no real damage, so follow it up.
Frag Grenades kill, while Flashbangs only stun. Molotovs are craftable and handle Freakers better. Keep a Flashbang for when you are cornered.
Attractor
The Attractor is a crafted noisemaker that draws nearby Freakers to it. You learn it after Do You Have My Back?. Use it to pull Freakers away or onto traps and bombs.
Attractor Bomb
The Attractor Bomb is a noisy explosive that pulls Freakers in before it goes off. Its recipe sits in the Wagon Road Ambush Camp bunker. It is the easiest way to group a pack and kill it at once.
Frag Grenade
The Frag Grenade is a military fragmentation grenade you cannot craft. Hot Springs, Lost Lake and Wizard Island sell them from Trust level 3. Use them on human groups behind cover and on tight Freaker packs.
