I'd suggest CLEP over StraighterLine. The reason being is CLEP is more likely to be accepted at colleges and would probably be quicker to on transcripts. If a college accepts CLEP they already know what it counts as and as soon as you finish the test the scores get sent. Your local community college might accept CLEP. Plus if you use modernstates its free. If you are looking for easy cleps I'd suggest analyzing and interepting literature, if you know math then college math, and if you know a foreign language try one of the languages.
StraighterLine is a little bit more hit or miss in terms of acceptance and even if a college does accept it they might not have a handy list of equivalencies which would mean manually evaluating it, this could drag out the process longer and it might not even work in the end.
But I think before you do anything it depends on your branch and your country. I don't know where you are serving. Also, sometimes the military gives out waivers. My brother is in the US Navy but he didn't try too hard in high school and had low grades. His job required certain courses (math and science) with a certain GPA. He didn't have that. However, he got a perfect score on the ASVAB so they gave him a waiver for the grades since he proved he knew his stuff. Maybe the same could be said for you. If you scored high marks on both your GED and military entrance exam maybe they will waive the 15 credits. I don't know though it all depends on your country, your branch and the specific job you are doing in the military.
