I couldn't finish 'em. Looks like this's gonna get complicated.
Straggler is an enemy in Final Fantasy Type-0 appearing in areas controlled by the Dominion of Rubrum. Two variants exist, one based a member of the Imperial Trooper family, the other a member of the RPG-155 Gunner family.
Stragglers with the Imperial Trooper base fire at the cadets with ranged fire power, and can be knocked down making them harmless before they can get up. Stragglers with a RPG-155 base, similarly, stay back and fire at cadets, but at a slower rate of fire.
Stragglers of both types are simple to defeat with very few physical or magical attacks. Particularly those with the RPG-155 Gunner base, can be defeated when closed in on.
