I know not a lot is known about Spartan IVs. I haven’t read Glasslands, but I’ve heard that Spartan IVs are volunteers similar to the ORION Project.
In the First Look video, the Spartan IVs appeared to move very much like Spartans from Halo 2 and Halo 3.
Now, if Spartan IVs are volunteers, and Spartan IIs were raised from the age of six to be deadly weapons, why do you think Spartan IVs would be almost or just as strong as Spartan IIs?
Speed =/= strength. Spartan II’s excel in all aspects of combat, though they specialize how they want to. I doubt the Spartan IV’s are as capable as II’s and even if they have better/similar implants (which I highly doubt) they don’t have the same amount of training.
So, I don’t think that they can be as capable as the II’s were, but they will still be a great step up from normal marines. Though, the technology of bio-engineering will have increased whilst MC has been inactive, making it much safer to join the SPARTAN program. But I would still place them below the II’s.
Augmentations have probably been made much safer since the time of the SPARTAN-IIs and the success rate is probably phenomenal.
Also, a good majority of the IVs will be the S-IIs and S-IIIs that have been integrated into the program.
Do you think the gameplay in campaign will match the gameplay in MM?
It would give me a weird feeling switching between MC and S-IVs if the gameplay was different.

Not only do I suspect many ONI agents to now be upgraded with the SIV formula, I also suspect the Rookie and Buck to be SIVs. Not too sure about the rest of the squad, but now that 100% success rate on all has been achieved (or so it appears), Buck is no longer a Spartan by spirit 
Derp I need to read other posts lol.
And most of the surviving II’s are stuck on a dyson sphere.

Spartan-II will not be integrated into Spartan-IV since spartan-IV is the Program all Spartans were integrated in the Spartan “Branch” of the UNSC. That being said Fred,Linda, and Kelly the Surviving Spartan-II’s Beside John are also kept from the Spartan-IVs reason being is that SPartan-IIs are more effective than the IVs and cannot be slowed down by Cocky/witty banter happy ODSTs and Marines that went through S-IV training.
Proof
Armor and Augmentation Differences -
Quite frankly SII’s are far superior in all aspects to SIII and SIV for the sheer fact that the MJOLNIR Systems that SII wear are not capable of being worn by another Other Spartans Because the Augmentations Given to those of the SII are of a Degree far Stronger and Much more potent allowing them to wear the Armor that they do. SIII majority wore the SPI which Simply putting it was just upgraded ODST at most; SIV had the MJOLNIR Shielding technology but the material and longevity of the armor was lighter and less protective which allowed them to move so freely in the armor; SII’s were also on average about 8 to 14 inches taller than Spartan IVs (You can see this in the Halo 4 campaign when chief walks beside the Spartan-IVs in the mission where you’re in Requiems forest just after you find them with captain lasky.
Personality and Communication differences -
Going back on to what others have Stated Spartan-IIs are desensitized; that being said which means they are all Business Spartan-IVs enjoy to make witty banter to not just themselves but to the fellow marines and ODSTs around them, Circumstantially this could Jeopardize a Mission if they stay on a com that is open or even if its closed in the case of covenant interference. Spartan-IIs only spoke if necessary and spoke on restricted coms and if they spoke on Open they Spoke in a code that only they could understand a secret that the S-II made between each other.S-II were anti-social to all Especially the ODSTs if any of you recall the engagement that happened between john and I believe it was 4-5 ODSTs in the boxing ring.
Training and Education Level Differences -
Now going onto their training a quote from the lady who made The S-IIs that saved the Human race Dr. Halsey considers SPARTAN-IVs to be inferior to SPARTAN-II’s because they haven’t undergone a lifetime of military training and indoctrination; this being said they are adults that Volunteered to be trained as spartans. (On a humanitarian level thats great but we’re talking about effectiveness in a combat Zone and that might not be enough sometimes.) Spartan-II were abducted at the ages of 5 - 6 and trained until the ages of 14 - 15, This is a minimum about of 11 years of solid Military Training; They trained with each each other as well as against each other and the infamous ODST Tango Company; as well to add onto the Advantages of the age when they were trained since they were children the time when the brain is young and like a sponge allowing them to learn quickly precise and fast; as well the Spartan-II received the highest degree of everything ranging in mathematics,Science,Physics, Other languages, Engineering and so many other subjects which made them Far superior on an intellectual scale compared to Spartan-IVs which may have received anywhere from a public education level to perhaps a private school education but then if they went to a private school the chances of them going to the military in any form by todays standards if the trend would be Hypothesized as the same would only be a 19% chance of going to the military.
Experience -
S-IVs have been active since the year 2553 maybe as early as the end of december in the year 2552 but definitely have been active since 2553 and halo 4 was set in i believe (correct me if i;m wrong i’m going off of memory right here) 2556 or 2557
Total Service time - 3 to 4 years
S-IIs have been active since the beginning of the human covenant war on February 11, 2525 Ending on a political notice as of December 11th, 2552 and on March 3, 2553 marking the End of the Human-Covenant war hostilities
Total service time - 31 to 32 years
Spartan II > Spartan IV
Juste compare the master chief with sarah palmer.She looks like a baby compared him

Actually it says that Spartan IIs and IIIs have been integrated into the Spartan 4s kind of like the IIs and IIIs were on reach
I think some Spartan IVs could at least pose a match against a III or even a II because it’s said Kelly runs 37 MPH without armor on and Sarah Palmer can run 30 MPH without armor. yeah that’s 7 MPH difference but it is very close and not to bad John can run full speed a little faster than 30 MPH but not as fast as kelly. That’s just one example that I can name off on the top of my head but Halsey did say “some are closer than others.”
anyone noticed that the elites or even covenant in general were weaker in h4 compared to the other games? ik this isn’t related to the topic but it just occured to me
Spartan II’s were indoctrinated and were trained to be warriors. Spartan IV’s were volunteer basis because of the political situation the Spartan II Program created. It is not as harsh either. Spartan II’s were often quite larger as well. I would bank on Spartan II’s being the best of the best. 
Depends really I think all III’s save gamma could be pulled apart in spi by a II but after reading last light and knowing what a GIII is capable of under stress I wouldn’t rule them out. Especially if you put a gamma in mjollinir
Obvious Spartan II
John, Kelly, Fred, Jorge…
