Though the most gargantuan of the great apes might be mistaken for unthinking beasts, their intelligence is demonstrated by their ground forces, who possess borrowed technology that they utilize with uncanny sophistication.

And command apes have been witnessed making use of radio communication devices to orchestrate attacks, despite the fact that the language they employ seems like nothing but gibberish to human ears.
