[Zechariah 14:2 KJV] "For I will gather all nations against Jerusalem to battle; and the city shall be taken, and the houses rifled, and the women ravished; and half of the city shall go forth into captivity, and the residue of the people shall not be cut off from the city."
[Zechariah 14:3 KJV] "Then shall the LORD go forth, and fight against those nations, as when he fought in the day of battle."...........This is Armageddon and corresponds to Revelation 19:19........... [Revelation 19:19 KJV] "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."
[Zechariah 14:4 KJV] "And his feet shall stand in that day upon the mount of Olives, which [is] before Jerusalem on the east, and the mount of Olives shall cleave in the midst thereof toward the east and toward the west, [and there shall be] a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south.".................These events occur at the end of the tribulation. Christ comes in the clouds. Christ remains in the air during Armageddon and afterwards, he touches down on earth, and stands on mount of Olives
