What is the best way to trainer Soldiers?

I'm trying to figure out what would be the best way to train my soldiers. Right now Im doing it with one soldier at a time on easy(cause it's the quickest of the mission), and Im really not getting were. Or we it be best to make a group and train on normal until I get the results I want?

its really hard training them

This one group I was training to of the people would level up like crazy but this one dude i have wouldn't level up at all.

ima try to hacks stats but btw do you know what the maximun hp is for not to cheat on last game maximun was 201 hp but now is harder how much is the maximun for a clean headshot? 402 hp?

Good luck on hacking stats. Actually I wonder if hacking a stat will also lock up PO+. I tried to hack items and the game froze, Konami and Hideo got really smart this time. I didnt know that you hp controls how well you're headshots are? I thought headshots were tied to your character stats in weaponry like in portable ops.

yup everytime you change a simple value it freezes sucks i know

This game is already hard, I guess it's preparing us for MGS 4.

lol i think MGS4 is gonna be easier 2 analogs=better aiming

True, but so well be better at sneaking around and avoiding battles. Because the fights in that seem pretty intense, especially since Gekkos will hopefully be involved. But this game is hard as crap, my goodness I wanted to throw my psp.

yea i like the original mpo better mpo+ only good because:

-more characters
-more stages
-and a keyboard to type wathever

thats it pretty much infinity sucks

Yeah, Infinity Mode does get kind of old after a while. But for some reason hard is not as hard as I thought it would be. I've beaten hard more time then I've beaten Normal. I will try Extreme next, but I want want to get some more Gurlokovic(Spelling, the ones from Sons of Liberty) Soldiers. I seen them a couple of times on Hard, but on hard all i get is mostly 1* soldiers.

i got a pretty good Gurlukovich soldier untrained 200 something HP

But the thing is I don't want to do Extreme now, I nearly lost everyone on the Ravine. Lucky for me I have a secret weapon, pulling the battery out of the psp. I might have to hack me some fultons, but I hate the fact that you have to drop the item out of your inventory and repick it back up, plus PO+ is DMA too. Konami did a number on this game.

yea infinity is hard all i do is bring 4 characters 2 with high stamina and 2 with high HP so when its a normal mission use the high STM to make a run for it unless there is a soldier worth it and when its a fighting mission use the high HP guys

yeah I realize that, but I have this team I use for everything. But infinity that a long time to do. Im a really lazy person as you see.
