Esper’s guidance authorizes the displays of the American flag, state and territories flags, the POW-MIA flag, the flags of other countries, unit flags, senior leader flags, unit flags, and flags flown for protocol purposes.
The new guidance treads carefully around President Trump’s previously stated opposition to a ban on displays of the Confederate flag by not authorizing an outright ban. Instead, displays are not allowed because it is not among the flags authorized for display and his guidance never mentions the Confederate flag.
