As in the insect world, so it is in the world of the Marro. It is a hierarchical structure; some lead, some fight, others work. In the Marro hierarchy, drones are the lowest. Nearly mindless brutes, Marro Drones perform all the heavy labor required. It is not worth the effort of developing advanced biological weapons for them, and thus they are given slashing spears, simple to manufacture and to use. In battle, they are herded forward in large expendable groups as cannon fodder. Often these groups will just mill about aimlessly, only some of the drones moving towards the enemy. But at times a group mentality will take hold and the entire horde will charge towards the enemy as one, posing a great threat.
