Let's try this route. Maybe you are more reasonable than I give you credit for or maybe not. I guess we will find out.
Suppose you are Ezekiel and that you are living in ancient times. And that you are then presented with visions of the future thousands of years away. Obviously, you are going to see things you have never seen before. Especially if these visions are involving the 21st century. Seeing these visions is one thing. Writing about what you saw is another thing since what you saw doesn't even exist yet. Now you have to describe what you saw and the only thing you can use to describe what you saw is via what you are already familiar with at the time.
If you saw missiles in the visions, for example, obviously missiles don't exist in ancient times. Therefore, you might use arrows to describe them, for example. Why not? Do not arrows get shot into the air and fly through the air? Do not missiles get shot through the air and fly through the air? There you go then.
To show how ridiculous you are being about Ezekiel 38-39 based on it using ancient weaponary imagery, are you going to apply the same reasoning to the following as well, where you already admit is still future?
Revelation 19:11 And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war.
12 His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself.
13 And he was clothed with a vesture dipped in blood: and his name is called The Word of God.
14 And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean.
15 And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.
16 And he hath on his vesture and on his thigh a name written, KING OF KINGS, AND LORD OF LORDS.
17 And I saw an angel standing in the sun; and he cried with a loud voice, saying to all the fowls that fly in the midst of heaven, Come and gather yourselves together unto the supper of the great God;
18 That ye may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses, and of them that sit on them, and the flesh of all men, both free and bond, both small and great.
19 And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army.
20 And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.
21 And the remnant were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh.
If Christ returns sometime in the 21st century do you seriously believe the battle will be involving literal horses? Do you seriously think the flesh of horses is meaning flesh of literal horses? Of course you don't. Why is it then that Revelation 19 can use ancient imagery describing the 21st century yet not literally involve anything ancient, but Ezekiel 38-39 can't? Per the latter it has to be literal ancient weapons, per your thinking.
But why? Because if it is, why is it that no Jew past or present has any knowledge of these events ever transpiring in the past? That would be like Americans, for example, that would know their own history, none of them knowing about a major event that supposedly happened in their history. Yet they are told by someone, such as you, that this major event did happen, though. Except no American past or present knows anything about it having happened in the past. That's really reasonable, isn't it? That you have insight about someones past history that no one else has.
