Martin is currently the S.H.I.E.L.D. Station Chief in Gotham city, tasked with monitoring what he can of those groups posing a threat to international security, and occasionally deploying on interdiction operations. His resources, while inventive, are limited, and he is willing to work (unofficially) with local law enforcement and vigilante groups in the city to accomplish his objective.
"Mushroom clouds are what everyone wants to avoid. The people who don't should be watched. Constantly."

Martin was born to a homemaker and an Investment broker, in an upper-middle class town in the midst of New England.
He was undermotivated in high school and partway into college, spending a bare-minimum of time on a Business Administration degree, and getting through an ROTC scholarship on the bare seat of his father's contacts.
Julia Fields was an on again off again paramour of his during college; in his Junior year, she became pregnant with his first daughter, Katelyn. This brought his carefree college career to a screeching halt.
While he did what was socially acceptable and married Julia later that year, he changed his plans to move to an Active position in the Army, instead of the reserves, pressing away from a marriage and fatherhood he did not want.
Martin was Army infantry, then Rangers, from 1992 to 1997, deploying from base to base stateside, including a tour of duty in Germany. The constant moving around took its toll on his family, which grew to include a son, Patrick, and another daughter, Nicole.
In 1997, Martin, then a newly minted Captain, was invited to an international team run by the IAEA, whose purpose was the investigation of missing or unsecured nuclear material in non-cooperative countries. He accepted this position, providing stability to his family at the expense of an effective separation between him and it.
Martin's decade in investigations turned him into an experienced and deadly operative, though promotion was slow going; one promotion to Major was given during this time.
7 years into his tour of duty, Julia, his wife of 13 years, divorced him. He still visited his children irregularly at best, his now ex-wife less still.
After a decade of service, a botched raid on a weapon smuggling operation caught Kavanagh in an explosion of a dirty bomb, heavily irradiating the area. The strike killed most of his team, and left him slowly dying in a hospital bed stateside.
The near-death experience left him with the aching need to connect with the family he had ignored for so long, but lacking the time to do any of it. An offer by S.H.I.E.L.D. at that time to serve in their organization, with access to the experimental treatments needed to keep him alive as a bonus, seemed like a heaven-sent gift.
Martin had been serving as a field agent for S.H.I.E.L.D. for the past five years, committed to a number of operations in the continental United States and other hotspots in the world with what's left of his team. He's recently been elevated to station chief in Gotham City, with his team disguised as a catering company. He holds a Lieutenant Colonel's commission in the USAR, and moves to fight for his country, while trying to make up what life he can with the loved ones he abandoned.
Martin is an expert in the use of most forms of firepower; he can operate any firearm of the modern industrial age, including pistols, rifles, SMGs, grenades, heavy weapons, and crew-served equipment. He prefers the use of compact machine pistols and assault carbines; generally things that can be used in close quarters, and both his profession and personal collection provide him with a wide variety of firearms to engage his skill.
Skill:Bush Pilot ( 4)
Thanks to operating in countries with bad roads and corrupt air traffic controllers, Martin has, by necessity, become a competent pilot of two classes of aircraft: small, single-engine aircraft, and helicopters, both armed and unarmed. He is not a combat pilot, however; send him against professional fighters or a dedicated SAM net, and he'll be in a world of trouble.
Martin, through military training and hard fought experience, is a deadly combatant in close quarters, either with knives, bayonet, or his bare hands. His skills are firmly based on a practical knowledge of human opponents, of where bones break and muscles fold. His style spends little time on showmanship or pains to grapple or subdue, instead seeking to cripple or kill his opponent as quickly as possible. Because of this, Martin would face trouble pulling punches, or engaging superhuman opponents.
Skill:Nuke Specialist (8)
The majority of Martin's pre-S.H.I.E.L.D. career, and a portion of his current one, has been spent hunting down nuclear weapons and the materials used to manufacture them. He can identify the signs that nuclear material is being hidden, detect attitudes that indicate someone's close to activating a device, and deactivating or dismantling said device, whether it's a dirty bomb built in someone's backyard, or a group of 8 MIRVs still loaded aboard an SLBM. This extends to many different nuclear delivery systems and payloads, including the ones that countries still has classified to all but the professionals using them.
Gear:Protective Systems (4-5)
Martin understands that the human body does not react well to bullets. Because of this, he's almost always wearing protective gear of some sort. When in civilian guise, this is limited to a undervest capable of stopping knives and street weapons. In full S.H.I.E.L.D combat gear, he can survive military-grade weapons, and is generally protected from NBC fallout and deployment.
Through many covert operations, Martin's captured the skill of losing himself in crowds, deflecting the suspicion that falls on him, and generally being invisible until the time comes to offer someone a drink and just ask them a few questions. He rarely breaks his cover, even when presented with incredibly stressful situations, and has both extensive training and experience in all manner of spycraft, from passing on messages via dead drops, to knowing what the numbers stations are actually saying, to the myriad of places you can find a firearm, a bed, and pain killers in an urban area.
Thanks to a long career Martin has a rough grip on the theory of combined arms, and knows how to move down a street, and clear a building without exposing himself to fire. He knows the proper syntax to use on military radio nets, and how to interact and relate to other soldiers, and quite a few other odds and ends of carrying a rucksack around combat zones for 15 years. He can also understand and converse in a number of Eastern European languages, with fluency in Russian.
Martin's cover is an amalgamation of his own personal life and a fabricated occupation at a S.H.I.E.L.D. front company dealing in catering and catering supply, with both a convenient location in Gotham and business dealings nationwide, where he serves in middle management. There's HR paperwork, W-2s, federal licensing, and squabbles with the union, properly stamped passports, contracts, everything needed to present a valid appearance to those without first-world intelligence resources. This also includes a CCW permit for a 9 millimeter revolver, as Gotham is a dangerous place.
Martin has three particularly S.H.I.E.L.D. agents that work for him, with their own codenames. Hepburn is a master at social infiltration and the fast talk; Antwerp is a silent and rather deadly melee specialist, and Ponzi understands numbers and financial paper trails better than a number of forensic accountants. All three of them owe a loyalty to him that’s more then their current occupation, and work to accomplish operational goals under Martin’s direction.
The drugs that Martin takes to manage the condition that is slowly killing him do offer one advantage; while he takes them, the effects of radiation on his body are lessened considerably, allowing him to take a larger dose of radiation without ill-effects. With advanced armor and radiation resistant clothing, he can survive for extended operations in nuclear hot zones.
As the Gotham Station Chief in S.H.I.E.L.D., Martin both has access to the high-tech tools of a covert operative and the combat kit of a less covert one, as well as the capability to call on the resources of subordinate organizations, and, if it comes down to it, heavy firepower. As a supervisory agent, he also has direct control of a team of agents with their own covers, able to be utilized to best accomplish assigned objectives.
The best spies make the worst human beings; they cut themselves off from any emotional ties, any bonds that could be grabbed by a near-omnipotent power and snuffed out like a candle. Martin, for all his strengths, lacks that isolation. While his kids are grown, and his wife has divorced him, he has spent a good amount of time trying to work on his connection with them and ensure that the next phase of his life doesn't ignore them. Unfortunately, this leaves his two daughters, son, and ex-wife as a weak point for those attempting to manipulate him. If pressure is placed there, short-term compliance may be had, and long-term plans forced to set in motion, though only a fool would believe a man as resourceful as Kavanagh remain under anyone's thumb for long.
Martin believes in what he's doing is right, and in the forces of Good defeating the forces of Evil. But he also believes in the big picture, and has seen enough people die that ending a human life in itself is no longer a barrier to him. If a threat is in front of him, and the death of combatants is necessary, he has no compunction in breaking limbs, backs, and necks to get to his objective.
Bureaucracy is a blessed, cursed thing. It allows you to call in assets from a dozen different agencies to make a man disappear, but requires 8 separate meetings and a pulped redwood to do so. Martin is a member of a government agency, and is bound to follow it's rules, and regulations. Sometimes, this means holding back actions that would save lives and catch terrorists to obey the letter of the law. It's stifling, and sometimes annoying, but, without it, they would be no different from the secret police of a banana republic.
Radiation never works the way you expect it to; for some, it grants them fantastic powers. For others, like Martin, it robs you of your life. He suffers from a rare disorder of the cells caused by radiation poisoning picked up on his last IAEA operation in Eastern Europe. Thankfully, he has a very healthy supply of SHIELD provided medication, and can last a week without it with little adverse effects. After that, cellular necrosis starts setting in at an accelerated rate. He has two weeks where a regimen of medication can be administered which would allow a full recovery, though he becomes tactically useless quickly. The fourth week will leave him incapacitated near the beginning, and dead of organ failure by the end.
