The message is a threat to the Cabal, The US army tweeting this coincidence is "activating" that specific Q drop, the Q drop implying something significant will happen next week (in March 2022, not 4 years ago).

This will no doubt make the Cabal panic and expend more ammunition, This way Q can keep them permanently guessing, and one day Q will be able to give us messages in plain site, and the Cabal will have no idea if it's an empty threat or the real deal.
