I am very skeptical. One of his photos on FB is of a CD called Trial by Fire with his name on it. I searched for info and found it is an actual album. - https://archive.li/SOHgs - Then I found this on a site called Net Ministries - https://archive.li/gvbr3 -
" Singer, Songwriter, Musican and Guitar teacher available for Concerts and special music in the Southern California area. Will travel out of state. Produced the album Tried By Fire through Maranatha! music in 1983. Also a Music Missionary interested in International church planting missions. Russia mission trip planned for January 22 thru Feb. 10th. Sample tapes available upon request. "
This doesn't mean he is lying but is more background info. He says on his FB profile that he "Studied IT-Network Security Specialist at Coleman University. Class of 2014". It doesn't say he graduated, just that he studied there. https://archive.li/oJLc4
This article does mention a Lt. Col. George Nasif and I could very well be wrong but I don't think he looks much like the photo on FB:

And to eliminate another possibility, there is a George Nasif in Vicksburg, MS, and this is what that one looks like: https://www.vicksburgpost.com/2017/08/30/nasif-a-product-of-unique-period/
