Interesting^^
I could swear it's the same as in M&M6, but you made me curious now, since I never played the Red Alert games. I always stuck to the Tiberium games...all three of them ;)
When I have the time I might just play both games and try to trigger and compare both sound effects, maybe I was ...

I like how you used a sound from "Might & Magic VI - The Mandate of Heaven" for entering the Uplink Station
And Eva of course
