Author of "military squad" SF podcast

I think that you may be thinking of Andy Remic.

This is a British author who has written some other fiction, including SF thrillers and a steampunk(ish) fantasy called the Clockwork Vampires.

There is a link to his blog from 2008, where it mentions that he is going to be reading one of his "Combat K" series of novel, on Podiobooks.

Combat K is a series of 4 (currently) novels set in a post singularity universe that follows the exploits of a former elite military unit lead by Keenan, along with his squadmates Pippa and Franco. The book mentioned in the link for the podcast is War Machine, the first in the Combat K series:

Extract from the podcast link website

WAR MACHINE- In a time of post-Singularity and FTL travel, Combat K are elite and murderous combat squads trained by the Quad-Gal Military specialising in interrogation, infiltration, assassination and detonation. Their gameplan is simple: to end The Helix War, which had raged across galaxies for a thousand years. Ex-soldier Keenan, a stocky battered war veteran, addicted to Jataxa spirit yet still horribly efficient at his job, is working as a private investigator on a planet at the peaceful fringes of the Quad-Gal. Following the death of his family, Keenan is riddled with guilt and self-loathing, and carries a need for revenge which consumes him. When a prince from Jervai Province offers him a case on a dangerous colony world in exchange for clues that may lead to his family's murderer, Keenan is dragged from his self-pity. However, to have any chance of success he must gather together his old military unit, a group who swore they'd never work together again... Through the tribal jungles of Ket, the mean chaotic streets of The City, the mission leads the squad to Teller's World, a Dead World, and home of the extinct God Leviathan... and there Keenan will find answers to his deepest nightmares... and face an ancient, evil terror older than The Four Galaxies.

Further with the mention of the name of the author getting confused with being Serbian or Bosnian, then I think that the surname Remic fits very well.
