Operational history
Entering service on December 5, 2557, Roland replaced Infinity's former shipboard AI Aine, who was destroyed when the ship crashed on Requiem in July 2557.

Second Battle of Requiem
When Fireteam Majestic arrived onboard Infinity shortly prior to the ship's second voyage to Requiem, Roland welcomed them aboard. He later gave Captain Lasky intel on the Covenant remnant fleet over Requiem. Later, Fireteam Crimson recovered a Requiem translocation artifact and brought it aboard Infinity, the artifact soon activated draining power from the ship. Roland was affected also, as his hologram flickered and he noticably slowed down when informing Captain Lasky of what was happening. When the arrived, Roland informed Lasky that it's captain was requesting permission to land. After Catherine Halsey returned to Infinity he locked down the engine room. Later he showed Lasky Fireteam Castle's fate at REQ-153-N. When Fireteam Crimson began chasing Jul 'Mdama, Roland helped them track him through the Slipspace portals, pointing out to Jared Miller, who was having difficulty with the portals, how easy it was. Roland enjoyed taking part in the op, "commanding" Crimson to go to where a portal was, later commenting how much more he liked running ops than ships. For Crimson's next mission at The Gate, Roland had to help Jared Miller run the op, as Sarah Palmer was unreachable. Into a series of missions, Roland found Gabriel Thorne's IFF tag near Crimson at The Cauldron, and tracked him to the Quarry where Crimson began searching for him.

After Dr. Halsey was detained for exchanging transmissions with Jul 'Mdama in secret from the crew, Roland appeared in her holding cell and questioned her on why she chose to withhold the information. Halsey then subverted Roland by speaking the code-phrase "undid-iridium", placing him under her complete control. She forced him to give her access to the ship's computer. Roland managed to free himself from Halsey's control and had her arrested, but not before Halsey had managed to contact Jul 'Mdama. Moments later, Prometheans began materializing all over the ship via the artifact, while Covenant forces attacked the ship from outside.

Initially, when Fireteam Crimson returned to the ship to assist in the battle, Roland was unable to communicate with them or Miller due to the artifact's interference. Eventually, Miller managed to reestablish contact with Roland, who helped Crimson seal hangar bay 450 from further intrusions. Roland then warned Crimson that the Covenant were planning to detonate several stolen nukes in the engine room, which he had initially failed to detect due to the warheads being cloaked. Roland assisted Crimson in locating and disarming all the nukes. Shortly afterwards, the ship's aft weapons went offline due to Covenant jamming. After Crimson destroyed the jamming devices, Roland was able to reactivate the weapons and drive back the attacking Covenant ships.

Ealen IV
In March 2558, Following Infinity's return to Earth and Captain Lasky's hearing at the UNSC Security Council, Roland interrupted Lasky's jogging session in Infinity's memorial park to notify him that Orbital Command alerted them of an inbound diplomatic shuttle. Admiral Lord Terrence Hood arrived on Infinity to inform Lasky he needed Infinity to provide security on a diplomatic mission to Ealen IV. During the peace talks, Infinity lost communication from the surface of the planet. Unbeknownst to the bridge crew, the delegation had come under attack by Covenant remnant forces. When Lasky managed to reestablish communications, he told all fleets in orbit to direct their ships to the planet in order to save the delegation. The fleets rallied with Infinity and forced the Covenant mercenaries into retreat.

Freighter ambush
Following the events on Ealen IV, Captain Lasky left Infinity to investigate the UNSC spy who leaked the location of the negotiations. Lord Hood remained onboard Infinity and requested a demonstration of Infinity's Forerunner engines. He asked Roland to plot a random vector with multiple headings but before Roland could, they were notified by lieutenant Jespersen of a distress signal near the Artesia-702 system. The exercise was scrapped and Infinity went to investigate. Arriving in the system on March 11, they found a damaged civilian freighter, the Pilgrims Pride. The freighter was tugged into one of Infinity's bays on Hood's order. An ambush was sprung when the freighter launched multiple assault crafts and set itself to self-destruct. With the help of Fireteams Majestic, Colossus, and Fenrir, the attack was repelled and the freighter was tugged back into space before it could self-destruct on Infinity. Following the skirmish, Infinity's after action teams discovered that the vessels used by the assailants belonged to a long-lost warship, the. Infinity's crew were having Roland put together a report on the ship, however, Hood told them not to waste their time as he knew all about the Spirit.

Trivia

 * Roland is voiced by.
 * Despite the 20th-century precedent of his avatar, Roland's name bears a tangential connection to the mythology behind the naming of Cortana. Roland is a figure in medieval legend with a sword named Durendal; Cortana is named after Curtana, the sword of Ogier the Dane, which bore the inscription "My name is Cortana, of the same steel and temper as Joyeuse and Durendal." Durendal, in turn, served as the namesake of a principal AI character in Bungie's Marathon series.
