It is led either by an Angel of the Lord, Jesus in angelic form (a Christophany), by the Archangel Michael, or by God Himself. Most descriptions of angels in the Bible describe them in military terms, such as encampment (Gen.32:1-2), command structure (Ps.91:11-12; Matt.13:41; Rev.7:2), and combat (Jdg.5:20; Job 19:12; Rev.12:7). Its specific hierarchy differs slightly from the Hierarchy of Angels as it surrounds more military services, whereas the Hierarchy of angels is a division of angels into non-military services to God. The heavenly host participate in the War in Heaven and, according to some interpretations, will battle Satan and Satan's own army at the End of Days and be victorious.
Biblical accounts 
Book of Joshua 
In the Book of Joshua 5:13-15, Joshua encounters a "captain of the host of the Lord" in the early days of his campaigns in the Promised Land. Some interpret this being to be an Old Testament appearance of the pre-incarnate Christ due to the fact that he allows Joshua to worship him, something angels never allow in the Bible. Others claim him to be Michael, and archangel and protector of God's people, Israel. This unnamed heavenly messenger is sent by God to encourage Joshua in the upcoming claiming of the Promised Land:
Once when Joshua was near Jericho, he looked up and saw a man standing before him with a drawn sword in his hand. Joshua went to him and said to him, ‘Are you one of us, or one of our adversaries?’ He replied, ‘Neither; but as commander of the army of the Lord I have now come.’ And Joshua fell on his face to the earth and worshiped, and he said to him, ‘What do you command your servant, my Lord?’ The commander of the army of the Lord said to Joshua, ‘Remove the sandals from your feet, for the place where you stand is holy.’ And Joshua did so.
Organization of the Heavenly Host 
Cherubim are depicted as accompanying God's chariot-throne (Ps.80:1). Exodus 25:18-22 refers to statues of two cherubim placed on top of the Ark of the Covenant. J. A. Motyer writes: 'the cherbim overshadowing the ark were a pedestal for the invisible throne of the invisible God'. Other guard-like duties include being posted in locations such as the gates of Eden (Gen.3:24). Cherubim were mythological winged bulls or other beasts that were part of ancient Near Eastern traditions.
This designation might be given to angels of various ranks. An example would be Raphael who is ranked variously as a Seraph, Cherub, and Archangel. This is usually a result of conflicting schemes of hierarchies of angels.
It is not known how many angels there are but one figure given in Revelation 5:11 for the number of "many angels in a circle around the throne, as well as the living creatures and the elders" was "ten thousand times ten thousand", which would be 100 million.
Angelic combat 
During the Rebellion, Lucifer's forces were defeated by the Heavenly Host led by Archangel Michael (Rev.12:7-9). Satan and his followers are believed to have or have had access to the throne of God, a freedom that the devil uses or used to accuse the followers of God (Zech.3:1; Job 1 & 2; Rev.12:10). Some believe that open warfare has already occurred and Satan is bound to hell, others believe that open warfare will not break out in heaven until the tribulational period (Rev.19:11-21) when the heavenly host will be commanded by Christ. See Book of Revelation
In the Tanakh (Hebrew Bible) 
In the Hebrew Bible, the name Yahweh and the title Elohim frequently occur with the word tzevaot or sabaoth ("hosts" or "armies", Hebrew: צבאות) as YHWH Elohe Tzevaot ("YHWH God of Hosts"), Elohe Tzevaot ("God of Hosts"), Adonai YHWH Tzevaot ("Lord YHWH of Hosts") or, most frequently, YHWH Tzevaot ("YHWH of Hosts"). This name is traditionally transliterated in Latin as Sabaoth, a form that will be more familiar to many English readers, as it was used in the King James Version of the Bible.
The term "Lord of Hosts" is also used in the Bahá'í Faith as a title of God. Bahá'u'lláh, claiming to be the Manifestation of God, wrote tablets to many of the kings and rulers of the world inviting them to recognize Him as the Promised One of all ages and faiths, some of which were compiled and published in English as The Summons of the Lord of Hosts.
In literature 
In the English epic poem Paradise Lost by John Milton, the Archangel Michael commands the army of angels loyal to God against the rebel forces of Satan. Armed with a sword from God's armory, he bests Satan in personal combat, wounding his side.
