In the Old Testament, an army of some 15,000 Midianites invaded Israel for the purpose of "hijacking" their food supplies.
A judge named Gideon called the Israelis "to the colors." Some 30,000 showed up to form an army that was probably large enough to defeat the Midianites.
Gideon was told by God to "downsize" his army by telling the volunteers that anyone who was afraid or "indisposed" to fight could go home. About two-thirds, or 20,000 did so, leaving Gideon with about 10,000 men, a smaller, but more "select" army than the Midianites had, because it had "sluffed" its weakest men.
God further told Gideon to take his remaining troops to the river to drink. Most drank by burying their face in the water, but a few knelt, and used their hands to lift water to their mouths. Gideon was told to use only the latter few, some 300 in all. These were supposedly the equivalent of "special forces" picked by God.
When they went to battle, they used unusual "shock and awe" tactics, blowing trumpets, flashing torches, and throwing stones noisily, rather than standard assault tactics using sword and spear.
Were these tactics, and the selection of 300 "picked" troops (1% of the original 30,000, 2% of the 15,000 Midianites, 3% of the later 10,000) at the heart of a "faith based" military operation? Gideon won, of course, but what was God's plan in using the special methods that He did?
