Equipment, and Grenades

 Equipment: Claymores: The holy equiment, possibly the best one there is. An almost imposssible to spot land mine, the deadly little box can kill multiple enemies in a nearly instantanious explosion. 2 nearly impossible to spot laser trip the explosive, and by the time you see it, its probally already exploded. Plant it in an entryway to a building, or in the middle of the map, it grants a free kill. Great for snipers, because it covers one entrance. The only counters are hacker and flak jacket. Ive managed to run over one with lightweight, as it explodes behind me , but thats only one. (Tip: Plant the claymore so it angles away from the door, so when an enemy runs in, it explodes behind them, this prevents the claymore from going off to early.)
                                   Jammers: This is the most misunderstood equipment. It jams enemy radar in its radius, acting as a miniature counter/spy plane. But thats not all! Equip hacker so you can find enemy equipment. When you see it, plant the jammer. A mostly unknown fact, The jammer actually disables equipment! It hacks claymores so they dont go off, and more! Sneak into a room unnoticed because their claymore wont explode when you get close to it!
                                    C4: Throw explosives that are triggured by a fuse. Great for traps, and plant them on a flag in domination, hide, when someone begings to take it.... BOOM!
                                     Camera Spike: Plant a camera that watches over a certain area. Enemies are outlined in white.
                                     Motion Sensor: This detects all non-hacker pro enemies in its short radius.
                                     Tactical insertion: Place you next respawn!
Grenades:          Semtex: This grenade sticks to enemies when thrown. Impossible to get off, their only hope is to take someone out with them, by charging the thrower. It also sticks to any surface, assuming it misses the enemy. It flashes and beeps as it flies through the air, and is heavy so it cant be thrown as far as frag's or twmahwks.
                                      Frag: This is a highly explosive fuse triggered grenade. You can cook it, to prevent it from being thrown back at you. Lighter than the semtex, it can be thrown farther, and is more explosive. It is also less flashy, so it can be thrown stealthily.
                                      TWMAHWKS!  Throw the retreavable haatchet at enemys, and it kills  them no matter where it hits them!Istant death, and it can be reused, the thing is utter shread! Cons: Incredibly difficult to use.
Tactical grenades:   Willy Pete: AKA smoke grenade. Does a small amount of damage, and puts up a smoke screen(IR scopes can see through it) Great for objectives. ( I have killed someone with it!)
                                                      Flashbang: Deafens, and blinds enemies with a bright flash for about 10 econds, depending on how close they are. They can still shoot but they cant see.
                                                       Concussion: Hinders enemy movement in its explopsion radius, and partialy blinds, and deafens them.
                                                        Nova: Dispuses a toxic gas that blinds, chokes, and hinders movement of enemy. Usually makes enemies rush outside, to escape the deadly fumes of the Nova 6 gas.
                                                          Decoy: Mimics gunfire, and confuses spyplanes and blackbirds causing extra enemy symbols to appear on the radar.
