MacMillan

"Oi, Suzy!"

- MacMillan before he melees an Ultranationalist guard.

Captain MacMillan, with the callsign of "Alpha Six" and later "Baseplate" (in Call of Duty: Modern Warfare 3), is a Scottish Special Air Service officer featured in Call of Duty 4: Modern Warfare and Call of Duty: Modern Warfare 3. He was the commanding officer of Alpha Team featuring then-Lieutenant John Price during the missions "One Shot, One Kill" and "All Ghillied Up", and in various missions in Modern Warfare 3, he has risen to the position of director of British special forces. He is popular among Call of Duty fans for his dense Scottish accent and sharp wit.

SAS career
"Look at this place... Fifty thousand people used to live in this city. Now it's a ghost town... I've never seen anything like it."

- MacMillan's description of Pripyat.

Around 1996, fifteen years prior to the events of Call of Duty 4: Modern Warfare, 33-year-old MacMillan was the commander of a two-man sniper team in the 22nd Regiment of the SAS which included then-Lieutenant John Price, who was assigned to assassinate future Russian Ultranationalist leader Imran Zakhaev, an arms dealer at the time. Price recalls that it was the first time the British Government had authorized an assassination order since World War II. The venue of the assassination was Pripyat, Ukraine, a once bustling town deserted 10 years earlier following the Chernobyl nuclear disaster. The peaceful surrounding countryside and Pripyat itself had become overgrown and derelict (with the radiation from Chernobyl still in some places) the least likely location for an arms deal.

Price and MacMillan were both issued ghillie suits and camouflaged, suppressed M21's for the mission, along with suppressed USP .45's. An M82 SASR was also used for the assassination attempt.

MacMillan and Price had to sneak through the countryside around Pripyat to get to Hotel Polissya, overlooking where the exchange would take place and an ideal spot for the shot. Ultranationalist guards, armored patrols, attack dogs and helicopters are all obstacles they either hide from or take out, depending on the player's inclination. MacMillan's knowledge of the radiation zones around the perimeter of their route is sound, and after a brief scare a "convention" of enemies arrives in Pripyat, MacMillan and Price make their way to the hotel. There they wait for two days for Imran Zakhaev to appear.

When Zakhaev eventually appears (right in front of the abandoned plant) with a suitcase full of money, Price and MacMillan prepared for the shot. After MacMillan gave Price ample warning of conditions that could impact the shot, such as the Coriolis effect, Price fired.

MacMillan and Price believed that they had killed Zakhaev; but they in fact only blew his arm off. Price and MacMillan quickly shoot down a helicopter and then rappel from the hotel, which is destroyed by a second helicopter. All went well for the British duo until an attempt to shoot down a helicopter ends in a serious leg injury for MacMillan, forcing Price to carry him. The duo fought their way through the darkening ghost town until finally reaching the extraction point at the Ferris Wheel.

Waiting for extraction, they set up Claymores, picking off countless Ultranationalist soldiers until their helicopter arrived.

Baseplate
MacMillan returns in Call of Duty: Modern Warfare 3, having now become the director of British special forces, ranked Major General operating in the Hereford, UK, headquarters as Baseplate, collaborating with MI5 and commanding the SAS operations during World War III and unofficially sharing intelligence with Captain John Price, as well as sending him equipment for his mission to find and kill Vladimir Makarov.

Call of Duty 4: Modern Warfare

 * In sniping missions in which the player controls Soap, Captain Price will occasionally say, "Nice shot, MacMillan would be impressed." This is usually heard in "Blackout" when giving sniper support to the Loyalists.Callofdutymaclarge1.jpg
 * In some earlier trailers for the game and on the back of the game case he is seen with a suppressed M4A1 instead of his M21. Originally, Infinity Ward gave him such a weapon, but they later reconsidered.
 * MacMillan will kick open the door to the church if the player constantly blows their cover but will open it normally if you don't.
 * If the player looks at his eyes from a certain angle, they can see that his eyes are a shade of blue.
 * If the player looks closely on one of MacMillan's boots, it is possible to faintly see the logo for the US Marine Corps.
 * During design and testing, Infinity Ward used test phrases that were never put on the game, but can be found on YouTube.
 * It is left unknown if MacMillan fully recovered from his injuries.
 * When Macmillan is put down behind the ferris wheel in One Shot, One Kill he is going to move back a bit but he will not be affected if he is shot or if a grenade explodes near him.

Call of Duty: Modern Warfare 3

 * MacMillan is 53, stands 5'11 (1.8 m), and weighs 162 lbs (73.5 kg) according to his dossier in "Return to Sender".
 * He refers to Price as "son" on several occasions, highlighting their close relationship. It's similar to when Price refers to Soap as such.
 * In the cutscene for "Return to Sender" Price tells MacMillan that: "You still owe me for Pripyat.", referring to when Price carried MacMillan when he was injured by the falling helicopter out of Pripyat in the Call of Duty 4: Modern Warfare level "One Shot One Kill".
 * MacMillan is mentioned as Baseplate in the subtitles.
 * The actor who voiced MacMillan in Call of Duty 4: Modern Warfare did not voice MacMillan in Call of Duty: Modern Warfare 3. MacMillan's voice is aged, due to the fact that it's been 20 years since Pripyat. Interestingly, Zach Hanks, the original voice actor for MacMillan is credited because he was the original voice actor.
