Guard Duty is an errand in Final Fantasy Tactics, available from chapter 3, "The Valiant" in Eagrose Castle after the battles at Orbonne Monastery. It is commissioned by Nalman, Larcan Mercantile.

The errand will take 11—13 days, costs 2000 gil, and finds a random artefact if successful. The best-suited job for the errand is the chemist, and sending a white mage boosts the success chance dramatically, however, errands will succeed if the player sends any three units for the maximum amount of days.

This is an appeal for protection to accompany our chocobo wains along the route from Eagrose to Dorter. In these truly troubled times, monsters have appeared on the trade roads and are beginning to threaten our caravans. Please protect the wains and the cargo they carry.

Nalman, Larcam Mercantile

Successful report[]

We responded to a call from Larcam Mercantile to protect their caravan from monsters. While fighting off one such attack, one of the chocobo wains overturned, spilling a large stash of prohibited narcotics. We questioned the driver over the matter, and he revealed that the company president, Nalman Hosse, a man aged one-and- forty, was involved in a drug smuggling ring and had ordered the shipment be sent. The city guard succeeded in arresting Hosse as he made to flee, and we received an unexpected reward for helping bring him to justice.
