Spartan II program due to the fact that great soldiers such as John-117, Linda-058(did I get that right?) and Frederic-104 came out of this program. yes the survival rate is 33/75 in first class, and second class numbers unknown, but the benefits of surviving are great. I'm not saying Spartan III's are not good, Noble team was amazing, but I believe surviving S-II is much more beneficial.
