Adding units to mission

[texasranger97]

Hello

I am trying to add some units in some of the games (vietnam, red tide) because some are way to hard and not fun anymore.
What I did was going to the editor F3 mode and adding unit to the mission then saving. I tought it would work but when i tried the misssion ingame, the units i added werent there.

If somebody could tell me who to do it, it would be very apreciated.

ps:also is there a way to change the unit description. (ex: officer, so i can give another term like squad leader.)
