You probably expected some kind of argument on this (but that will be later)
This mod add the possibility of winning a medal after mission and under certain conditions

fulture inprovments:
- more medals to winning
- more conditions to be met to win a medal 
- what comes to my mind

time to return between the living

1.1: Fixed an issue with a modification and add alternate Medal Of Honor And Merit Medal
thanks Olliekun and KeketteX for report
1.2:Infinite Heaven Edition 
conditions can be changed in the Medal Of Honor Menu in the Infinite Heaven (only ACC)
1.3:Remove IH module because doesn't work
contitions you can edit manually

the new version sure works because I tested it many times

there is some glith to award Distinguished Service medal 
I don't know how it works
I tested the mod in infinite heaven r257

DIY custom contitions 
1.Open mgsv file (winRar or 7Zip)
2.Go to \Assets\tpp\script\lib and open TppResult.lua
3.Go to line 288
4.you will see 
if t==TppDefine.MISSION_CLEAR_RANK.S then
    TppMotherBaseManagement.AwardedHonorMedalToPlayerStaff() 
   end
if you want more contitions to award medal just add more variables for example
if var1 and var2 and var3 then
 TppMotherBaseManagement.AwardedHonorMedalToPlayerStaff() 
[TppMotherBaseManagement.AwardedMeritMedalPointToPlayerStaff()]-merit medal award for playable character
end
5.save

you can put two different funtions for example 

if t==TppDefine.MISSION_CLEAR_RANK.S then
    TppMotherBaseManagement.AwardedHonorMedalToPlayerStaff() 
end
if t==TppDefine.MISSION_CLEAR_RANK.S and svars.bestScoreTime>0 and svars.bestScoreAlert>0 then
    TppMotherBaseManagement.AwardedMeritMedalPointToPlayerStaff()
end

all conditions
