It's the Vanguard glider that costs 540MP.
Commandos glider costs 500MP.
Inf commandos cost 440MP iirc'
Btw, note that UKF demo has worse radius than the other two demos (USF and Soviet one).
Speaking about demos. I do not know if someone suggested before, but how about demos help deny blobs and single capping squads is that they inflict a forced fall back like the propaganda artillery along with high damage inflicted to the squad.
Thematically I would say the initial exploding would cause high suppression and damage. Then say a three second delay, so that the animation of the explosion can finish, the pinned squads will auto retreat.
