Based on how the story goes in the light novels, I'd say from start to finish the arcs would follow more or less this pattern (not necessarily with these names):

Titan's Son arc (Mammon in Shiganshina, Kuklo enslaved by the Inocencio family)

Shiganshina arc (Kuklo and Sharle escape, Kuklo sneaks into the Survey Corps, Kuklo is arrested by the MPs)

Industrial City arc (Kuklo meets Cardina in prison, Jorge rescues them and brings them to the Industrial City, Kuklo begins testing the improved 3DMG)

Training Corps arc (Kuklo and Cardina join the Training Corps, official 3DMG training begins with the trainees)

Survey Corps arc (Kuklo and Cardina join the Survey Corps, Carlo leads an expedition outside the walls to put 3DMG into practice)

I've noticed the manga has really expanded on the story though, so there might be more plotlines or events that would change how the arcs after the Industrial City would play out.
