Sgt. Daniel "Reck" Recker  is a US Marine and the protagonist of Battlefield 4. He becomes Tombstone's squad leader after Baku.

Biography
Not much is known about Recker's background. According to Pac, Recker, Irish, and Dunn "go back a long way." Dialogue from Captain Garrison implies Dunn trusted Recker the most.

Baku
Recker and Tombstone was sent to Baku, Azerbaijan to retrieve information about the Russo-Sino relationship. Ehen a trade with RGF operatives goes bad, Tombstone regroups and fights their way to their extraction point. The mission ultomately results in success of capturing the intel, but at the death of their extraction pilot, Hawkins and the squad leader, Dunn.

Shanghai
With Dunn's death, Recker now led Tombstone. They were later sent to Shanghai, China to recover VIPs and a CIA agent Kovic in the Zhi You Tower. Kovic and the VIPs were found after defeating much Chinese resistance. They were delivered via captured helicopter to the USS Valkyrie whilst Tombstone had to take an alternate transport. Fighting their way through the Chinese military once again, they took passage aboard a civilian ferry to the Valkyrie.

South China Sea
The following day, Recker, Pac, and Irish were summoned by Garrison for a briefing of the recent events. Along the way, they witness the USS Titan which had been recently boarded and nearly destroyed. Garrison sent Tombstone along with Kovic as temporary squad leader to investigate. Tombstone retrieved the Titan's voyage recorder and began to return to the Valkyrie, repelling the invaders along the way. The Chinese had already attacked the Valkyrie by the time Tombstone arrived via a DV-15 Interceptor. They had picked up Hannah whilst making their way back to Garrison. The voyage recorder was successfully delivered, but at the cost of Kovic's life.

Singapore
Recker again led Tombstone, along with a volunteered Hannah, to Singapore. Their objective was to fire a flare over Changi Airport for the Valkyrie. They had initially began the assault with several tank elements and other Marines, but all were lost and otherwose left behind by the time they reached the airport. Tombstone was successful in firing the flare, but evidently too early as they were caught in the subsequent fire during their escape. While Pac, Irish, and Recker were disoriented, Hannnah betrayed them and captured them with several Chinese soldiers.

Kunulun Mountains
Recker and Irish were brought to the Kunlun Mountains for interrogation and imprisonment. With the help of his cellmate, Recker escaped his cell and caused a riot within the prison, which they used tommask their escape. Recker and Irish eventually came upon Hannah who had rescued them. The group then used a tram to escape, however a helicopter attacks them, only killing Dima.

Tashgar
Irish, Hannah, and Recker than made their way to Tashgar, in western China. They schemed with US Marine Molina to meet with Major Greenland after arriving in the town. After fighting off numerous Russian soldiers, Tombstone had finally met Greenland, who ordered them to destroy a dam to flood the Russians' positions. Once this was successful, Greenland provided transport for Tombstone to the Valkyrie.

Suez
Tombstone arrived at the Valkyrie on the Suez Canal, in Egypt. They parachuted onto the runway and counterattacked the Chinese soldiers. Tombstone eventually met up with Jin Jié, Garrison, and Pac (who presumably covertly escaped his own prison) in the Valkyrie's medbay. Jin Jié pursuaded the remaining soldiers to stand down, but Chang still posed a threat. Hannah, Recker, and Irish volunteered to deliver a RHIB loaded with C4 to sink his warship. When Recker pulls the trigger, thr C4 doesn't explode in malfunction. He can either pick Irish or Hannah to trigger the explosives, but result in their death. If Recker takes too long, Chang will destroy the Valkyrie, and everyone aboard. The game ends no matter what choice is picked.

Trivia

 * In both the Gameplay Reveal Trailer and the E3 2013 singleplayer trailer, Recker shared the same first-person model as Henry Blackburn and the USMC multiplayer classes (with the exception of Assault) from Battlefield 3. In the Battlefield 4: Official Single Player Story Trailer and the game's final release, Recker's first-person model is the same as the U.S. Marines in multiplayer. This being, Oakley gloves and multicam fatigues.
 * His gloves in the E3 trailer, however, were different from the Oakley Assault Gloves that Blackburn uses.
 * He appears to have some familiarity with tanks, as he commandeers one in Singapore.
 * While driving a RHIB in third person, the back of Recker can be seen.
 * In Baku, when Recker checks his loaded magazine to see it empty, he can be heard swearing in a quiet tone. This is Recker's only dialogue for the entire game. This can be heard here.
