Why there is no 'in' in the sentence "Nuclear launch detected" Please change 'in' to 'has been' Thank you all in advance. I've been into Starcraft. I think you guys know the famous game made by Blizzard. By the way, Whenever I play Starcraft, There is something that pops up in my head. It is the quote, " Nuclear Launch Detected." I've learned that 'detect' is a transitive verb, So it must have an objective to complete the sentence. For example, The researchers detected that there had been a volcano eruption. But why on earth that Terran commander say (I'm not sure if the man(woman) is a Terran commander or not) "Nuclear Launch Detected" I've Googled it. But I couldn't find any answer.
