There is a second and more complete tutorial about Infantry Sequences that BobingAbout wrote, and i think xgamerīs ART.INI guide covers it too. (Theyre at the same tutorials page you saw)
My wild guess (as i cant recall the frames in the graphic), is that you should use ClegSequence and add code lines for deploying frames and further modifications...as its almost based everyway on the Chrono Legionnaire.
