Please Help the Old man, Against the tide

[moby43]

Single player, I have beat all of SC3, I have gone back SC2, all I have to beat is Against the Tide and I have beat it all. I can get in the building with 4 guys and perfect health, I can be at 0 seconds with 4 guys at perfect health, I have the hostages at Zulu, I have killed at least 2 snipers, probably more, the game will not end, I have thrown red smoke when I am told to, the helicoptor pilot has told me he will be there in 20 seconds tango's will eventually kill all my guys or me. I am at my wits end, i am doing something wrong. I have beat this level 5 times already, but not on Admiral please, please help.

It's a game glitch - that happens sometimes to me too when I do it.

Throw another red smoke when that one goes out on the same spot and it should fix itself.

Thanks a bunch, I'll go at it again. How many snipers are up there?
