It's not just the CUP units, it's any mod i use i have tried loads. No inf units spawn at all. can you give me your mission file and i will add your mods and see if it works please?

@Murdock @CDEEKS Do you have a space behind the Faction Name? "CUP_B_US_Army " <--
That will mess your Factions up.
Can easily happen with some copy and paste work.
If that is not working, then try to use another faction. BLU_F for Starters. If that is not working, you got something messed up other than the faction itself. I'm not sure if the CUP_B_US_Army has Groups and such defined already, which could lead to that error you had too.

I have checked for spaces ,still doesn't work. The BLU_F works no problem and i have tried every single faction listed on the Wiki. It's weird because i have rolled my version back to an older version of ALIve like was suggested to me and it seems to spawn the aircraft of the custom factions but nothing else. so i am at a total loss as to what's going wrong. About 6 months ago when i was alway playing ALIVE i never had any issues like this. But i have read that due to some changes in the Code in new versions it's now not possible to use many custom armies with this mod.

I'm having a huge problem adding custom armies to my alive missions, would someone please upload one of their missions so i can check the set up with my one? Thank you.

I have been using the ALIVE mod for a long time last year, i had no problems what so ever. Now with the latest version not one single custom army works. I have tried all from RHS and all from CUP. Using as it shown here. http://alivemod.com/wiki/index.php/Supported_Factions

I'm relly at a loss as to WTF is going on, no matter what faction i use i keep getting errors can someone please help me?

Please help, i can't add any custom armies to my ALIVE missions. Every time i add the faction names it always spawns in Opfor from vanila arma 3. I used RHS mod us and russian forces . I have also tried east vs west mod along with a rhs insurgancy mod, all i get is errors at start up and it spawns default forces... I used to play this mod last year with no rpblems using RHS escalation, i'm using the faction names from the ALIVE wiki.

I know it works fine for the most part when using vinila units. Only when calling custom reinforcements it delays or somtimes never arrives.

First great mod, had it in my game for months and never bothered to try it out. I have been taking the last 4 days to test it out.
I'm now trying to add combat support module to my mission , i can't seem to call in any reinforcements using my custom RHS units.

USMC (D) ect , it works fine when i request normal BIS bluefor units but for some reason when i try to ask for US army units or any other custom units it gets stuck on "Request acknoladged stand by" , sometimes it will deliver them but like 20 min or so later.
