As I suspected, or may have already known from others, D5 appears to mean DECLAS. A "D" followed by 5 letters. Q uses "DECLAS" extensively.
After this drop, Q never used D5 again. I figure this is because anons had figured it out; meaning that "D5" could no longer be used to confuse the enemy.
There are 17 posts that mention D5
Think Mirror D5/5D
Nothing can stop what is coming. 5D is coming. 5th-dimensional consciousness is coming.
How do you still not know this???

he's too quick dismissing the unfamiliar (to him, at least) because it doesn't fall into a certain category he's used to.
Oh look! A sock puppet.
