If a Ranger with the Hunter subclass takes the Attack action to make a weapon attack, and then makes another attack using Horde Breaker, can they move between the two attacks?
The related rules are below.
Player's Handbook, p. 93. Horde Breaker. Once on each of your turns when you make a weapon attack, you can make another attack with the same weapon against a different creature that is within 5 feet of the original target and within range of your weapon.
Player's Handbook, p. 190. Moving between Attacks. If you take an action that includes more than one weapon attack, you can break up your movement even further by moving between those attacks. For example, a fighter who can make two attacks with the Extra Attack feature and who has a speed of 25 feet could move 10 feet, make an attack, move 15 feet, and then attack again.
