Here is a picture of all of the flags from August 2017. All branches of the military are present.
Many people have already mentioned that the military flags represent the fact that we are at war. While that is probably one meaning, it doesn't explain the use of 3 US flags and 3 presidential flags. Total of 10 flags.
Could these flags represent the Q Team?
POTUS + less than 10; only 3 non-military. Drops 60 and 1788.
Presidential flags = 3 non-military members (including POTUS)
Marine flag = 1 high level Marine member
Army flag = 1 high level Army member
Navy flag = 1 high level Navy member
Air Force flag = 1 high level Air Force member
US flags = 3 members of Military Intelligence (NSA, DoD, etc.), or lower level military members
"The director of the NSA is a military officer of flag rank (i.e., a general or an admiral) with a minimum of three stars."
