Mithidrates Roman Camp (Location)
A military encampment in Herakleion Nome, and part of the Recon Work side quest.
The camp treasure is actually in the stern of the docked boat. Snipe the guard on the dock, then climb up the stern and dropkill the guard below.
This gives you easy access to the red treasure chest.
The low houses here make it easy to kill the captain as well (if you don't just want to shoot him). Hop from roof to roof to get a vantage on him.
Dropkill for location completion.
