In an Attacking & Mobbing context Group-Advance may be preceded by Freezing, Periscope-Trunk, Bunching, Head-Swinging, Standing-Tall and Reach-Touch and Rumbling.
A Group-Charge is the result of Coalition Building. Initiating individual(s) may rapidly approach their companion(s) coming along side her/them in parallel or face-to-face, they may vocalise in chorus, while High-Fiving - Rapid-Ear-Flapping, sometimes with Tusk-Clicking, Trunk-Twining and engaging in reciprocal Trunk-to-Mouth. Then, in unison, they Group-Charge the affronting individual.
In a Group-Charge against another group of elephants, it is typically an older female, often the matriarch, initiating the coming to aid of a younger family member who may have been kidnapped or attacked.
