You can code in ILS/ICLS to any runway in DCS by editing the beacons.lua in each terrain. A bit time consuming and it's only a user side mod, not server side if you want it to be there for everyone. Not sure if it breaks IC or not. I've done it for 6 of the maps.
If you want to put a mod in to allow fields to put out ICLS signals I made this.
Beacons/ICLS mod
And I don’t know how many times a real world Hornet pilot needed to tell you but you’re wrong. They don’t have it and they don’t use them. ICLS only in the fleet.
1. I downloaded this info Excel and had it feed me frequencies as I made a few of the TACANs into VORTACs.
2. For Anapa I was chasing a bug that ended up being something totally unrelated.
3. The ICLS I wanted to keep away from ones I was using in missions that conflicted with the land based ones.

Krasnodar is actually 94X, readme is incorrect.
