 Experiences during the summer of 1966, most notably the War Zone C battles at Srok Dong and the Minh Thanh Road, in which 1st Division forces had destroyed enemy ambushes with storms of fire, had confirmed for DePuy the wisdom of this approach.To find the enemy during Attleboro, DePuy intended to have his troops sweep forward in a series of methodical tactical maneuvers called cloverleafing, employed when enemy contact appeared imminent.Typically, the unit would move forward on an assigned azimuth and then stop to set up an "overwatch" position, whereupon one squad would advance 50-100m, depending on the density of the jungle, while another squad moved a like distance to one flank.
