שופטים, פרק י״ח, פסוק כ״א

The migration of the Danites to the north was not merely a military campaign, but the complete relocation of an entire community. Confident in their ability to conquer a new city and settle there, the six hundred armed men traveled with their families and all their household belongings [רד״ק, ביאור שטיינזלץ].

After taking the idol from Micah's home, the group turned and resumed their journey [מצודת דוד]. As they marched, they carefully organized their formation. The children, the flocks of animals, and all the heavy baggage [רד״ק, ביאור שטיינזלץ] were positioned at the very front of the camp. This property consisted of large, cumbersome loads that could only be moved slowly and with great effort [רש״י, מצודת ציון].

Placing the most vulnerable members and the slowest-moving property at the head of the group was a deliberate tactical choice. The armed men anticipated that Micah and the local residents might pursue them to reclaim the stolen items. By arranging the camp in this manner, they ensured that in the event of an attack from behind, the children and the heavy loads could safely continue moving forward. Meanwhile, the armed soldiers remained in the rear guard, perfectly positioned to intercept and fight off any pursuers [רש״י, מצודת דוד, אברבנאל].
