So how does one get this translation from this
 

For nine whole days he shot his arrows among the people, but upon

the tenth day Achilles called them in assembly--moved thereto by

Juno, who saw the Achaeans in their death-throes and had

compassion upon them. Then, when they were got together, he rose

and spoke among them.

Εννημαρ μεν ανὰ στρατὸν ωιχετο κηλα θεοῖο
τηι δεκατηι δ' αγορηνδε καλεσσατο λᾱὸν Αχιλλεύς·
τωι γαρ επὶ φρεσὶ θηκε θεὰ λευκωλενος ῾Ηρη· 55
κηδετο γαρ Δαναῶν ὁτι ῥα θνηισκοντας ὁρᾶτο.
Οἱ δ' επεὶ ουν ηγερθεν ὁμηγερέες τ' εγενοντο
τοισι δ' ανισταμενος μετεφη ποδας ωκὺς Αχιλλεύς·


Why is no mention of "straton" made?

I see flying weapons traveling among the people, meaining arrows being shot, but they sure make it harder than it has to be.

You're right. It's not a great translation. straton means army, but otherwise it seems okay. I suppose an army is made of people . . .
