I was just highlighting the overall strengths of the SIII program. I know Jun is from Alpha Company and Tom and Lucy are Beta. An yes, only Gamma has the neural augs. The augmentation process wasn't perfected until Gamma Company as well--there were still some "washouts" in Alpha and Beta. I don't know where you got your info, but the only surviving SIIIs are Tom, Lucy and Jun. and maybe you're right about Osiris being a match for Osiris--only a Gamma SIII would have a guaranteed edge over them...and they're all dead.
Spartan II and III are both children trained to be soldiers. The difference is the armor. III's don't have full power armor and II's do....Spartan IV's are a mix of II's and III's while most are experienced soldiers given a augmentations and power armor while in adulthood. The augmentations take years to get use to and the longer you have them the better they become. Therefore on a level playing field with all the same armor. I would say II's and III's are even in some areas while the IV's don't come close.
No they aren't? Again have you read Halo: Last Light? Team Saber isn't dead, they and the rest of the Gamma Company IIIs were marked KIA in official records to allow them to operate covertly without any risk of exposing their illegal brain mutations.http://www.halopedia.org/Team_Saber
Also the augmentations of the Spartan-IIIs, Project: CHRYSANTHEMUM
, were 100% successful the first time. Alpha and Beta had no augmentation washouts, they had preliminary training washouts due to the training being tougher and the canidates being slightly younger than the Spartan-II canidates.
Also, 300 of the 315 Spartan-III Gamma Company
members were deployed from Onyx to battlefields during the war, the remaining 15 stayed on Onyx to compete for the Company's top honors. Those 15 were Teams Saber, Gladius and Katana. Gladius was wiped out, two members of Saber were KIA, and Katana ended up in Cryo sleep. When they were rescued from Onyx, Team Katana was supposedly resucitated.
The teams mentioned in Reach; Gauntlet, Red and Echo, all helped civilians off of Reach. With the deployment general withdrawal of most of the UNSC a forces at the time, it's safe to say they escaped.
17 Headhunters were in rotation as of 2552; Jonah, Roland and two others were KIA, there are no records of the others dying. 13 by the end of the war. And actually, you assume the role of a Spartan-III Headhunter team in Spartan Strike, so they are still active post war.
And Gamma's brain mutations would only help extremely against a Spartan-IV of they were on the verge of going into shock, they main purpose of them was to help the Gamma IIIs continue fighting and almost immune to pain when they were probably about to die. Dante was able to keep fighting for a few minutes with a gaping hope in his side. If the Spartan-III was close enough to death to have the extreme benefits kick in, then it probably wasn't going well for the III.
