在其中一集中Jonas在未知的情況下擊斃了身為游擊隊的老友，關于此事影射了啟發The Unit著作的Inside Delta Force作者Eric Haney在洪都拉斯培訓該國特種部隊的經歷，在書中表示他曾經直接參與過和當地共黨游擊隊的地面戰斗，在一次伏擊中他親手射殺了一名游擊隊指揮官，在搜查其文件時發現其為Enrique 'Keekee' Sáenz（ 真名：David Arturo Báez），前美國陸軍特種部隊士官，曾經參加過Delta Force的甄選。和Jonas一樣，Haley也懷疑Enrique在為游擊隊服務的當中仍舊私下和美國政府有所來往。雖然此事引發了不少爭議以及受到部分特種部隊隊員的否認，但仍舊在本劇中呈現了出來。節選自原書的內容：    I rolled the man onto his back and looked him over carefully before checking him for documents. He would have been a handsome man in life. Medium-sized and tightly muscled, with a deep chest and wide shoulders, he had the perfect build for a soldier. I gazed at his dirt- and gunpowder-covered face as I closed his glazed eyes. Jimmy had finished sweeping the perimeter. After positioning his men, he came over to where I was kneeling in the dust. I held up a hand and stopped him before he could give his report. ―Jimmy, take a long look and tell me if you think you‘ve ever seen this man before,‖ I asked as I thumbed through the various papers I had found in the pockets of the corpse. I pulled out a Nicaraguan military ID. ―Jesus Christ, Eric. You know who that is? That‘s Keekee Saenz. You remember him, don‘t you? He was in my Special Forces class and he went to Selection with us. I thought I‘d heard he went back to 3/7 Special Forces in Panama.‖ I turned the ID card over and read the name on the front: ―Capitan Enrique Eduardo Saenz-Herrera.‖ Enrique Saenz-Herrera, staff sergeant in the United States Army Special Forces. I remembered him from Selection as a quiet, competent type. A professional. I didn‘t get the opportunity to know him very well, but I had enjoyed talking with him on several occasions. I remembered now—he had been cut from Selection on the Day of Disappearances. Now he was gone for good. Dead. On a godforsaken, nondescript mountaintop, in a remote and utterly worthless part of the world. And I had killed him.     Something about this was badly wrong, and I was beginning to feel dirty and used. Some of the nagging little oddities about this mission started to come together in my mind. Like why the CIA had pushed so hard for this operation, and why we had been denied other support. As always when dealing with those people, it was a good chance I wouldn‘t receive any satisfactory answers, but I was as hell going to have a serious talk about this whole mission with the CIA‘s chief of station when I got back to Tegucigalpa. But I couldn‘t stop to dwell on my thoughts just now, for there was still much work to do.
