Okay dudes, have a look at this .
All credit goes to Dixon13 and SpyderBlack723 (and also ARJay for the marking units script).
What it does
This will add the possibility of dropping three tiers of intel items next to killed units of the asymmetric side of your choice and one tier to the other side (presuming you are playing as BLUFOR).
For the asymmetric faction, it will either (a) temporarily reveal nearby installations, (b) temporarily reveal all spawned units of that side, or (c) temporarily reveal installations further away. (Working on something better but this is what I've got so far).
For the non-asymmetric side, it will create intel items next to dead bodies that temporarily reveal spawned units of that side.
My preference is to set the percentage chance of this to (a) 10, (b) 3, and (c) 1. You can change this yourself according to the instructions at the top of the fnc_intelHandlerEast.sqf or fnc_intelHandlerGuer.sqf scripts. You can also change the object spawned by editing these scripts according to the instructions in them.
Be warned: the objects can be really hard to find in grassy areas. I think this creates a more realistic experience as you have to search for them, but if this is irritating then change the object to something large like a laptop. Unfortunately I haven't had the time to try to get an alternative way of spawning items to work properly just yet so the items spawn in a 3 meter radius. Ideally I'll reduce this and post a revised version when I get the chance.
How to use it
Add the stuff from either the AsymEast or AsymGuer folders to your mission root folder, using AsymEast if the asymmetric side is OPFOR, or AsymGuer if the asymmetric side is Independent. Obviously, if you already have an Init.sqf or Description.ext then just copy the code over from this into your original files.
Be warned, this should work but I haven't had the time to test it and I've done a few edits to clean it up from an experimental thing I was (very slowly) working on. Let me know if there are any bugs.
To test, set all the percentages in the fnc_intelHandler scripts to 100 and kill some guys in an ALiVE mission.
