The United Nations Space Command would like to thank all the involved navies for transmitting the bios accordingly. Also note that these are unaltered from the transmissions received from the respective nations.
His original assignment with the UNSC involved fighter operations aboard the UNSC's only carrier. During this time he acquired his star navigation comets, qualifying him for starship piloting and command duties. With the outbreak of the Third Solar War, he was promoted to fighter squadron command, and won several awards for his peacekeeping and combat duties, including one ugly incident versus his old navy.
He received his Captaincy in 2169, and was transfered to starship duty, there being a shortage of qualified captains at the time. (Many of the captains in the UNSC returned to their home navies at the start of the Third Solar War.) He quickly rose through the ranks, starting with a destroyer and ending as flag captain for the UNSC Home Fleet. He received his flag in 2178, and distinguished himself by destroying a rogue Islamic Federation squadron that outmassed his squadron almost two to one when the IF squadron fired on his ships.
He is one of the last chameleons in UNSC service, and is distinguished by having both Command Pilot wings and Master Navigator Comets. He has served in his current position for six months, advising the Secretary General on naval affairs, and acting as a high level ambassador to the navies of the Earth. He is the current favourite to be selected as Chief of UNSC Operations, when Admiral Carter's term runs out in two years, though other rumours have him being placed in charge of the UNSC response to the mysterious Kra'Vak threat.
The highs and lows of his career have made him known, at different times, as 'Iron Hill', 'Iron Heart', and 'Iron Head'. He has been a favorite interview for the interstellar newsgathering organizations, as he can almost always be counted on to make comments that require immediate retraction, elaboration, or armed response.
Adm. Izenberg is only recently retired, and has delved into his racing and dueling hobbies in earnest. Psychometric evaluations are green, but subtext analysis hints at submerged self-destructive tendencies born of long years of combat, politics, intrigue, and fatigue. Rumors that he may be re-activated to assist against the Kra'Vak threat are greeted with equal parts enthusiasm and trepidation.
Adm. Izenberg also holds the dubious distinction of having been the only commander on record hit in combat by 7 P-torps from ships under the command of Adm. Mark 'Indy' Kochte (and have those hits do considerable damage). Despite this, Adm. Izenberg's forces prevailed and won the encounter, though no one can really say why. Both NSL and NAC are lucky it was just a wargame.
Admiral Kochte has served the NAC with distinction over a thirty year career, culminating in his current position as CO, Task Force 56. His hobbies in the service are legendary, being the only Flag Officer with a talent and desire to mountain climb.
Just as legendary is his inability to hit one of the mainstay weapons of the NAC, the pulse torpedo. Normally, this would scuttle ones' career quickly; but the weapons he can use, he uses with style and panache, earning the respect of his friends and the wariness of his enemies.
One of his greatest contributions to the service was the creation of the Alternative Tactics programme at NAC Sandhurst, examining the use of different technologies and the changes in tactics that result. In particular, he was a pioneer in the examination of heavy beam weaponry (or the "red beam o'death"), and the resulting change in tactics that would result. He has also served under the Third Space Lord, Bureau of Ships, examining new and updating old technologies.
The men under his command are doing extra simulations and live-fire exercises, but other units have tried the same drills with only marginal success. Some crew members have brought forth the notion that Adm. Teske is somehow controlling his crew, enhancing their actions through the use of some "all-powerful Force", but this theory was later discounted when the crew brought forth their 'proof': ancient science fiction books. Still, his talent remains a mystery, though it remains to be seen whether it will carry itself over into this simulation.
