Authorities initially classed the mass murder as ‘workplace violence’ but it has since been acknowledged that the attack was an act of terrorism . Earlier this year, it was ruled that victims will be honored with Purple Hearts - awarded in the name of the President to those wounded or killed, while serving. But one victim claims he is still going without certain benefits after the Military rejected his claims that his injuries were sustained in the line of duty, Fox News reported. Staff sergeant Shawn Manning, who was shot six times with two bullets still in his body, told Fox News: ‘I think it's almost unheard of for someone to receive the Purple Heart but not have their injuries deemed combat-related. Honor: Fort Hood victims are set to receive Purple Heart medals today . ‘I know that was not what Congress intended to have happen, but it is what currently the Army has determined is going to happen.’ Manning, who says he suffers from Post Traumatic Stress Disorder, applied to the Army in the hope his injuries would be recognised as having been sustained in the line of duty – but this was rejected by a physical evaluation board. A letter he received said that the 2015 National Defense Authorization Act did not offer combat benefits ‘for service members permanently disabled in attacks inspired or motivated by foreign terrorist organizations.’ He says the decision means his family will miss out on $800 a month in benefits – as well as back pay – and fears other survivors of the shooting rampage will be in a similar position. An Army spokeswoman told Fox News that Purple Heart Medal recipients would receive benefits ‘to which they are legally entitled’ under the terms of the National Defense Authorization Act 2015. She added: ‘In the case at issue, no final decision has been rendered, and the Soldier will have a full opportunity to present evidence at a formal hearing.’ It is now known that prior to the attack, Hasan had exchanged emails with Anwar al-Awlaki, an al-Qaeda spokesman.

The U.S. is leading the war against terrorism which in reality is a war against Islam.' Hasan was convicted by a military judge in 2013 in the killings, and he recommended the death penalty.
