Arrian\'s \"Ektaxis kat\' Alanon\" transl issue

[Macedon]

Hmmm.. a third issue came up right now :

"ἀντὶ δὲ τῶν θωράκων Κιμμερικὰ χιτώνια, ἴσα καὶ ὅμοια τοῖς θώραξιν" (34.6.1.)

"instead of thorakae (they wear) Cimmerian chitonia, the same in appearance to the thorakae."

Can the Cimmerian chitonia look like a thorax?

Now the "isa kai omoia" part can also mean a more general "exactly the same", but the "in appearance" seems to me closer to Arrian's intention.

edit : What I failed to write was the fact that this was in the Tactica and NOT in the Ektaxis...
