High Explosive is the second mission of the Echo tier in Special Ops, and the twenty-second mission overall in Call of Duty: Modern Warfare 2. It takes place in a Favela of Rio De Janeiro in Brazil, from Takedown. The objective is to kill ten Juggernauts using only explosive weaponry and a knife. The player, however, can briefly use the M9 pistol when he is downed.
In High Explosive, the player(s) must neutralize all ten Juggernauts using only explosive weaponry; the player can't pick up or use non-explosive weapons, both in solo play and co-op mode, aside from the M9 if one is downed in co-op. The player is given a knife, a Thumper, an RPG, Frag Grenades, Flashbangs, Claymores, and C4. Three ammo crates are placed throughout the level for acquiring more ammo: one at the starting point, one in the middle, and one to the north-east. Neither claymores nor C4 will be replenished by said crates; and Juggernauts will not drop their weapons when killed.
It is possible to get on the rooftops and kill Juggernauts from there as seen in this video ; the main problem is reloading. However, the player can simply aim for the Juggernaut's head, making this a breeze on Veteran.
It is possible to spawn camp the Juggernauts and force them to stand still as seen in this video, by getting into the truck at the start of this level. However, one will have to eventually exit the vehicle to trigger more Juggernauts and to reload, so this may be a bad idea on Veteran.
