[b]Name:[/b] Matthias Makinen
[b]Rank:[/b] Corporal
[b]Specialization:[/b] Reconnaissance, Sabotage, has some medical experience
[b]Appearance:[/b] Standard-issue ODST Ballistic Battle Armor. Heavily damaged; stripped of non-essentials in favor of mobility and a lower profile. Little more than a lightly-armored battle-dress uniform. 

[b]Personal psych report:[/b] Focused, disciplined. If he speaks a word, be sure to ride your luck to the bank. A rough life may have given him the strong qualities of a soldier, but it's stripped him of everything else. He's cold, but efficient and resourceful. Deep down there's a cheerful man with the wit to brighten your day - I just haven't found him. Extreme dislike and distrust of ONI personnel.

[b]Career history:[/b]

(Pretend the [s]strikethrough[/s] is black ink and that the timeline was written by an officer, hence the personal comments)

[b]Timeline:[/b]
[i]2530:[/i] Born on Eridanus II, amidst the chaos of the Covenant attack.
[i]2531:[/i] After a period in refugee camps, relocated to Mars with surviving parent (father).
[i]2538:[/i] [s]ONI intelligence suggested father maintained link to Eridanus Rebels, believing father may have a role in recently uncovered plans against UNSC facilities. Threat of impending attack leaves no time for further investigation. Target is eliminated. ONI admits judgement error. Father was innocent.[/s]
[i]2538:[/i] Adopted by uncle.
[i]2546:[/i] [s]ONI intelligence uncovers uncle recently established link with Eridanus Rebels.[/s]
[i]2546:[/i] [s]ONI operatives make contact with Makinen, encourage him to become involved in uncle rebel activity and force him to provide intelligence on group under threat of dire consequences should he not comply. [/s]
[i]2547:[/i] [s]ONI carries out an attack on a rebel outpost using intelligence provided by Makinen. Uncle killed in blast.[/s]
[i]2547:[/i] I adopt Makinen. [s]Has suffered enough. Under my protection now.[/s]
[i]2548:[/i] Enlisted in UNSC Marine Corps.
[i]2549:[/i] Training finalized, transferred to Force Reconnaissance with the 3rd Marine Expeditionary Force.
[i]2549 - 2550:[/i] Assisted in the evacuation of civilians and military forces on Paris IV. Later participated in several counter-insurrectionist operations. Distinguished himself.
[i]2550:[/i] Transferred to NAVSPECWAR upon finalizing ODST training.
[i]2550:[/i] [s]They've got their claws on him again.[/s]
[i]2550-2552:[/i] [s]Infiltrated Eridanus Rebels as an ONI operative. Intel provided proved useful against the rebels soon after. They tossed him aside afterwards.[/s]
[i]2552:[/i] Participated in the reinforcing of Reach during its fall. 
[i]2552:[/i] Assisted with the evacuation of civilians and military forces on New Jerusalem.
[i]2552:[/i] Transferred to 1st Recon, 7th Marines on Mars.

[b]Weapons:[/b] M6C/SOCOM pistol, standard-issue combat knife.

([b]Note:[/b] I made up the 3rd Marine Expeditionary Force. If there is an established canon unit that is suitable for him, let me know. And for the record, he is not ONI and has never technically been an ONI operative. He was basically used by ONI for about a year to gather intel on the Eridanus Rebels because they know he is familiar with them and may have met some of the rebels in his teenage years. The intel he gathered may have helped in the operation that toppled the rebel leader that same year (or a year later, I forget), when a group of Spartans attacked their stronghold under the supervision of ONI.)
