A British man who called himself “Supaman” was sentenced Tuesday to seven years in prison for his role on the front lines in Syria with the terror group ISIS – which he left after feeling bored and cold.

ISIS goes through great lengths to promote its training camps in vacation-like brochures and videos, but Mohammed Uddin, 29, was crestfallen upon his arrival in Syria in 2014. He reportedly found the food “bland,” and he did not enjoy the cold-water showers and was "doing absolutely jack [nothing]," according to The Independent.

Authorities reportedly said that a “vast amount of work” went into Uddin’s investigation, which led to Uddin pleading guilty to a charge of preparing acts of terrorism, which carries a seven-year sentence.

The Crown Prosecution Service, CPS, said Uddin worked hard so his trip to Syria would go undetected. He reportedly messaged his friend back in the U.K. to talk about how “piss easy” it is to go undetected into Syria.

“U need to get used to the cold water and no electricity. Everyday use cold water, u will probably get your first shower when u get to your mudhafa [annex]. The house u stay in before the muaskar [training camp]. It’s tough bro lol, A LOT of patience is required [sic]," Metro UK reported.

Uddin, who is from Barking, Essex, reportedly did not spend too much time in Syria -- from Nov. 4, 2014 to sometime around Dec. 12, 2014 -- when he returned to Turkey. He was stopped by authorities in Gaziantep, Turkey, and was sent back to London’s Gatwick Airport, where he was detained.

“Online searches had been carried out relating to 'Islamic State fighting,' which strongly implied a more sinister purpose to his trip. Rather than a holiday as he claimed,” Sue Hemming, the head of special crime and counterterrorism at the CPS, said.

ISIS, which now controls large parts of Iraq and Syria, has killed thousands of civilians in the past two years. Along the way, its fighters have destroyed whatever they consider contrary to their interpretation of Islam.

Despite its grip in the region, it appears to suffer from cracks in its infrastructure. To be sure, Uddin’s complaints are not the first ones that describe the group as unorganized, prone to infighting in the ranks and poor food quality.

ISIS made efforts to attract fighters, like giving fighters a $1,500 marriage bonus and effectively employing social media to attract recruits. Twitter recently announced that it shut down more than 125,000 accounts that belonged to terrorists.

Hasan Hasan, a resident fellow at the Tahrir Institute for Middle East Policy and co-author of “ISIS: Inside the Army of Terror,” told FoxNews.com that ISIS recruits often arrive in Syria and find something different from what they expected. One of the hallmarks of ISIS is overrunning rural towns marginalized by wars in Iraq and Syria. ISIS gives these towns a sense of security.

He said despite Uddin’s claim of poor living conditions, ISIS is still operationally strong.

Hasan said ISIS would like to recruit everyone, but its focus is on children, which can keep the fight going on for the next generation and teaming up with other established jihadi groups in the region already committed to the cause.

“The well-experienced fighter is ISIS’ best option to grow and ensure its resilience in the future,” he said.
