Read the 5th trumpet in Revelation 9 and see the obvious descriptions:
Star = leader = Titus
Heaven = government authority = Rome
Earth = land that is the subject = Judea/Jerusalem
Locusts = army (see Jeremiah 51:14 for example)
Those not sealed = people that didn’t believe Jesus/also didn’t flee like Jesus told them to
5 months = the length of the siege
Like horses = army rode on them
Crowns of gold = Roman helmets
Human faces = Roman soldiers
Hair like a woman = tassels on helmets
Lion’s teeth = the Roman cheek guards
Iron breastplates = Roman armor
Noise of wings = flapping of metal shoulder feathering
Tails like scorpions = spears they carried
Apollo = the god of Titus’ Legio XV Apollinaris

The next event would be the crossing of the Euphrates by the additional armies, which happens to be the 6th trumpet, complete with the correct colors on the soldiers
