Thanks for translating a new chapter.
I saw that there are several instances of the verbs being used in the wrong tense:
-ed verbs are in the past (there are also irregular verbs like went
example given:
"The fourth and fifth group, went in from the right wing and killed them for me!"
This is an order and says something they should do now, it does not describe something they have already done.
The correct form would be: "The fourth and fifth group, go in from the right wing and kill them for me!" (went -> go; killed -> kill)
(Also I would drop the "The" in the beginning but that's just a personal preference and with or without is correct)
