The terms Theocratic Warfare (God ruled or God directed warfare) and spiritual warfare (spirit directed warfare or warfare engaged in for spiritual interests) are used interchangably. Here are some recent references:

Jonathan himself was also a fighter for righteousness. He had declared that "there is no hindrance to Jehovah to save by many or by few." Why? Because Jonathan recognized that there is always a need to seek divine guidance for victory in theocratic warfare. When Jonathan unwittingly committed an offense for which Saul sentenced him to death, he humbly accepted that judgment. Happily, the people redeemed him.—1 Samuel 14:6, 9, 10, 24, 27, 43-45.

Since the shedding of blood was so clearly forbidden, why was it that Jehovah permitted, and even commanded, the nation of Israel to engage in warfare? We have to remember that this was a sanctified warfare by means of which Jehovah, the Judge of all the earth, had demon-worshiping nations exterminated. The Canaanites, for example, were squatters in the Promised Land and followed a demonistic, immoral life-style that would endanger God’s holy people. Jehovah had the land "vomit" those depraved humans out of their territory, using theocratic warfare to have it done. (Leviticus 18:1-30; Deuteronomy 7:1-6, 24) This justifies the spiritual warfare of the Christian today.—2 Corinthians 10:3-5; Ephesians 6:11-18.
*** w05 9/1 p. 28 Let Jehovah’s "Saying" Safeguard You ***
True Christians are engaged in spiritual warfare. They contend with powerful foes—the invisible rulers of the present wicked system, who are described in the Bible as "the world rulers of this darkness, . . . the wicked spirit forces in the heavenly places." (Ephesians 6:12; 1 John 5:19) God’s people continue to be victorious—but not in their own strength. All credit goes to Jehovah, who safeguards and instructs them, as stated at Psalm 18:30: "The saying of Jehovah is a refined one. A shield he is to all those taking refuge in him."

Because the Greek soldiers at Marathon closed ranks and held on to their shields with all their might, they won despite overwhelming odds. Likewise, Jehovah’s loyal Witnesses are assured of complete victory in their spiritual warfare, for that is their "hereditary possession." (Isaiah 54:17) Hence, let each of us continue to take refuge in Jehovah by maintaining "a tight grip on the word of life."—Philippians 2:16.
*** w05 10/1 p. 9 Highlights From the Book of First Chronicles ***
In the days of King Saul, the tribes east of the Jordan defeated the Hagrites even though these tribes were outnumbered more than 2 to 1. This was because the valiant men of these tribes trusted in Jehovah and looked to him for help. Let us have complete confidence in Jehovah as we carry on our spiritual warfare against formidable odds.—Ephesians 6:10-17.
As always, make of it what you will.
