This will not completely answer the question because there is considerable debate about how to understand this prophecy under the sixth trumpet. However, here are some facts that we can deduce from the text.

1. The released angels are not necessarily "fallen angels". Indeed, they could be angels of God sent to destroy as occurred in various other times such as 2 Sam 24:16, 17, 1 Chron 21:12, 15, 16, Ps 78:49, 1 Cor 10:10, Heb 11:28, Ex 12:23, Rev 14:18, etc.

2. Indeed, we observe in Rev 9:15 says that these destroying angels "have been prepared for the hour and day and month and year" suggest that God had them ready/prepared for this exact point in time. This hints that they might be four of God's angels and thus not fallen angels.

3. Under the fifth trumpet (Rev 9:1-11) the angels (these are definitely fallen angels) that harm can only harm those who do not have the seal of God (V4). Eph 1:13, 4:30 say that the seal of God is accomplished by the Holy Spirit. Thus, the angels in the fifth trumpet can distinguish between those sealed by the Holy Spirit and those who are not. (Compare Rev 7:1-3.) Whether something similar applies under the sixth trumpet, we are not told.

4. It is not clear whether the events described under the sixth trumpet are alluding to some historical battle or a yet future battle. The former is unlikely as the size of the mounted troops is 200,000,000 - larger than any army that has ever existed! Thus, this is likely to refer to either a yet future event or a spiritual battle not intended to be taken literally.

Expanding on the last point, a non-literal spiritual battle is more likely because the power of these horses (V19) is in their mouths and in their tails. Thus, it is not the riders that cause harm but their horses and the power of the tails appears to be alluding to Isa 9:15 where the tail refers to prophets who teach lies.

4. The voice that commands the four angels comes from within the temple of God, and from between the horns of the altar of incense; this presumable depicts the voice of God commanding these angels.
