This script offers an easy to use Fat Cow functionality, for both SP and MP.

For the AI version, simply place a map marker, label it "fatcow" (not case sensitive) and, depending on your coalition, either a CH-47 (blue) or a Mi-26 (red) will be spawned.
The "Fat Cow" will by default be spawned 10 miles out in a random direction. After landing it will erect a temporary FARP - the default time is set to 20 minutes.
Spawn distance and duration can easily be adapted by the user.

Alternatively, use the second script and deploy a human controlled Fat Cow.

The script offers:
+ easy to implement, just load in a trigger as DO SCRIPT FILE
+ detailed quick start guide
+ versions for AI and human controlled Fat Cows
+ automatic differentiation whether the Fat Cow was requested by a blue or red player (AI)
+ temporary refueling and repair point whereever you need it
+ limited rearming capability
+ Multiplayer compatible

Enjoy!
