Greek camp

[hoplite14gr]

Flags and banners appear in the Hellenistic Age way later than the time frame you have in mind.
Spartans had access to good iron from Pelana.
Utensils in the Royal house hold might still be bronze but others would most probably made of iron.
7th century means mostly fighting your neighbors.
Plutrach says that Lycourgos set up camp rules and camp fortification.
Consider that these guys treated Iliad like the Gospel. Homer mentions perimeter pickets ans early warning patrols so they most probably used them

The important tents were the King's, the Herald's, (The herald would also execute bugler's duty) and the Sheer's/soothsayer's. Probably they would be marked by their respective shields being that the entrance of the tents Contemporary art shows folding stools and folding tables. Tripod with coal might be in the tents. Maps are very debatable subject. Sleeping rolls animal skins but probably no beds.

Hope I helped.

Kind regards
