In the Jewish canon, Daniel was not included among the prophets, but was instead considered literature. In "Matthew," Daniel is anointed as a prophet:
[Mat 24:15 NASB95] [15] "Therefore when you see the ABOMINATION OF DESOLATION which was spoken of through Daniel the prophet, standing in the holy place (let the reader understand),
In the Catholic canon, the Daniel scroll is divided into ten sections, but in the Protestant canon, there are only seven. That is because of the inevitable desire of fraudsters to associate their ideas with a heroic figure by producing new chapters to the original.
>…The Hebrew Bible includes Daniel in the Ketuvim (writings), while Christian biblical canons group the work with the Major Prophets.[4] It divides into two parts: a set of six court tales in chapters 1–6, written mostly in Aramaic, and four apocalyptic visions in chapters 7–12, written mostly in Hebrew;[5] the deuterocanonical books contain three additional sections, the Prayer of Azariah and Song of the Three Holy Children, Susanna, and Bel and the Dragon.[6]…

This is significant because Hebrew word "ge-bor" was used differently by Aramaic
speakers than it was by Hebrew speakers. Hebrew authors tended to reserve ge-bor for poetry, involving men mostly as warriors, but Aramaic authors tended to use the word to refer to men in more general terms. So since all of the references to ge-bor are in the Hebrew section, we should probably consider the word choice to be significant. IE: Daniel is not just speaking about males, but specifically about macho men. IE: Men that have or are expected to wield power, militarily, financially, socially, geopolitically and so on.
So I might suggest a translation along these lines:
[Dan 8:15-17 SUGGESTED BY BILL ROSS] [15] When I, Daniel, saw the vision, I tried to understand it; and, (picture this,) a man dressed like a warrior was standing in front of me. [16] And I heard the voice of another warrior between [the banks of] Ulai, and he shouted, "Gabriel, explain the vision to this man." [17] So he came closer to where I was standing, and as he approached me I became terrified and fell on my face; but he said to me, "Soldier, understand that the vision pertains to the time of the end."
So Hebrew Daniel had the angel Gabriel in front of him when a human voice from the middle of a canal/river commanded Gabriel to explain the vision. Human and with authority over angelic soldiers? This authority is given to men in Daniel:
[Dan 7:22 KJV] [22] Until the Ancient of days came, and judgment was given to the saints of the most High; and the time came that the saints possessed the kingdom.
[Rev 20:4 KJV] [4] And I saw thrones, and they sat upon them, and judgment was given unto them: and [I saw] the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received [his] mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
[1Co 6:2-3 NASB95] [2] Or do you not know that the saints will judge the world? If the world is judged by you, are you not competent [to] [constitute] the smallest law courts? [3] Do you not know that we will judge angels? How much more matters of this life?
However, Daniel had no authority, so it must be the Messiah, who acts as the God's voice/utterance/LOGOS and as the Captain of the LORD's Armies:
[Psa 8:4-6 NASB95] [4] What is man that You take thought of him, And the son of man that You care for him? [5] Yet You have made him a little lower than God, And You crown him with glory and majesty! [6] You make him to rule over the works of Your hands; You have put all things under his feet,
[Psa 29:3 NASB95] [3] The voice of the LORD is upon the waters; The God of glory thunders, The LORD is over many waters.
[Eze 43:2 NASB95] [2] and behold, the glory of the God of Israel was coming from the way of the east. And His voice was like the sound of many waters; and the earth shone with His glory.
[Rev 1:15 NASB95] [15] His feet [were] like burnished bronze, when it has been made to glow in a furnace, and His voice [was] like the sound of many waters.
[Rev 14:2 NASB95] [2] And I heard a voice from heaven, like the sound of many waters and like the sound of loud thunder, and the voice which I heard [was] like [the sound] of harpists playing on their harps.
[Rev 19:6 NASB95] [6] Then I heard [something] like the voice of a great multitude and like the sound of many waters and like the sound of mighty peals of thunder, saying, "Hallelujah! For the Lord our God, the Almighty, reigns.
[Jos 5:14-15 NASB20] [14] He said, "No; rather I have come now [as] captain of the army of the LORD." And Joshua fell on his face to the ground, and bowed down, and said to him, "What has my lord to say to his servant?" [15] And the captain of the LORD'S army said to Joshua, "Remove your sandals from your feet, for the place where you are standing is holy." And Joshua did so.
