The mercenary team was a six-man unit of former military trained soldiers hired by Charles Widmore to board the freighter, Kahana. They were lead by former marine, Martin Christopher Keamy. The mission of the mercenary team was to capture Ben Linus, kill anyone surviving on the island, and then torch the island.
On the freighter
Michael, posing as a deckhand named Kevin Johnson, witnessed Keamy, Omar, and two other mercenaries along with one of the freighter's crew skeet-shooting off the deck. When Michael questioned Keamy about the need for firearms on what he had thought was a rescue mission, Keamy snidely dismissed him. ("Meet Kevin Johnson")
On the Island
The mercenaries fatally shot Karl and Danielle Rousseau and took Alex hostage as the three were hiking to the security of the Temple. ("Meet Kevin Johnson") Upon coming to the sonar fence protecting the Barracks, they forced Alex to deactivate it. Unbeknown to them, Alex did so using a duress code which informed those in the Barracks that the fence had been shut down under threat. ("The Shape of Things to Come")
The mercenaries commenced an assault on the Barracks, shooting and killing Doug, a blonde woman, and Jerome. It is presumed they shot and killed all other unnamed Oceanic Flight 815 survivors who followed Locke to the Barracks for its security. They destroyed Claire's house with a rocket launcher, though Claire survived the explosion and was rescued from the rubble by Sawyer. The mercenaries then ceased fire as Sawyer brought Claire to Ben Linus's house, revealing Ben's hiding place. ("The Shape of Things to Come")
Next, the mercenaries released Miles from his imprisonment in the boat house, giving him a walkie and sending him to Ben's house. Keamy used the walkie to negotiate with Ben, ordering him to come out and give himself up to the custody of the mercenaries. After Ben refused, Keamy directed Ben to watch as he held Alex at gunpoint, threatening to kill her if Ben did not give himself up. When Ben still refused to comply, Keamy executed Alex with a gunshot to the head, in Ben's plain view. ("The Shape of Things to Come")
Ben promptly summoned the Monster, and it indiscriminately attacked the mercenaries. While Keamy screamed orders for the mercenaries to fall back, one unfortunate mercenary, Mayhew, was dragged back into the jungle by a tendril of the Monster. ("The Shape of Things to Come")
Mayhew was thrown 50 feet into the air, causing him internal injuries, leaving him bloodied and unable to walk without assistance. He later died of his wounds shortly after the helicopter flight back to the Kahana. ("Something Nice Back Home") ("Cabin Fever")
After stopping for a brief respite back on the Kahana (allowing Omar time to strap a device to Keamy's arm and for Keamy to read the secondary protocol), the five remaining mercenaries returned to the Island after the shooting of Captain Gault. ("Cabin Fever")
Upon arriving on the Island five kilometers from the Orchid, the mercenaries handcuffed Frank to the helicopter and set off to the Orchid to await Ben's arrival, as predicted by the secondary protocol. Ben eventually did arrive, surrendering as a diversion so that Locke could sneak into the station. Keamy then knocked Ben out with the butt of his pistol. ("There's No Place Like Home, Part 1")
The mercenaries, with Ben as a captive, returned to the helicopter, and were preparing to leave when Kate appeared from the jungle, surprising the mercenaries. Almost immediately after her appearance, the whispers began and the mercenaries fanned out into a defensive formation. Despite their precaution, the mercenaries Kocol, Lacour and Redfern were taken down by knives, bolas and electrical weapons as the Others ambushed. Under the intense gunfire, a grenade attack killed Omar, leaving only Keamy to chase Ben as him and Kate sprinted into the jungle. Keamy almost caught up to Ben as he tripped, but was tackled by Sayid, and engaged in a lengthy hand to hand melee. He was stabbed by Sayid, and then shot four times in the back by Richard Alpert, who appeared from the jungle with a Luger. Afterwards, Kate, Sayid, Ben, Richard, and the Others left Keamy presumed dead in the jungle.
However, Keamy was wearing a bulletproof vest, and snuck off into the jungle, returning to the Orchid with nothing but a combat knife to capture Ben. There he encountered Locke, who asked to talk, before being hit from behind by Ben with his telescopic baton, and then stabbed with his own knife. His death caused the Kahana to explode, marking the end of freighter mercenaries. ("There's No Place Like Home, Part 2")
