In most of these lines this is not grammar at all but the little startled noise Koreans write as 엇, meaning oh or oops, which starts two of the quoted sentences here. Two more lines are the barked military command meaning attention, and the rest are stylised sound effects and deliberately misspelt words. Nothing here establishes an ending with a meaning, so this entry stays open.
The examples below did not fully pin this one down — read them before relying on the entry above.
