You can scare the shit out of people if you fly past them. I don't know about you, but it's good enough of a reason for me to spend (a very large number) of rubles on it.
Buy one? Yes. But what use does it have in the military, it looks like a huge speed boat with two or three guns and some missiles.
I think I outlined the chief benefits of using an ekranoplan. As a super-speedboat, it produces very little noise (the Caspian Sea Monster's eight engines are only used on takeoff, it uses just two or four in normal flight), is obviously very fast, does not trigger minefields, doesn't easily show up on the radar, and still has enough lifting force and carrying capacity to either drop off a sizeable strike team (with tanks) or simply pack a good punch with a cluster of anti-surface missiles. Basically, it can operate as any frigate or missile cruiser - while travelling at 500 kph and not caring about such trivial things as reefs or shallow waters/flat islands. It still can cross land, especially if it's a type B like the Orlyonok (The Lun is a type A, unfortunately) - the same limits apply to normal hovercraft. But if hovercraft WILL be stopped by any construction over a meter or two high, ekranoplans can clear ten to twenty meters at speed, even the Type A ones.
(to clarify - Type A is a strictly surface-bound craft with no ability to change altitude, Type B is a "jumper" that can temporarily lift off but cannot fly by itself, and Type C is just a plane that's also an ekranoplan)
And, btw -
Soviet Hrenot'en would beat both Obyekt and Thingie:)
QFT. I'd sig it, but I need everything I got there.
