Allies: Kota’s Militia

Antarian Rangers have an ongoing relationship with Kota’s Militia from Order 66 to some point into the Purge (no date is given). First, “when Order 66 was given, a squad of Antarian Rangers (…) managed to ferry Kota and many of his soldiers into hiding” and in an ongoing fashion, working alongside Kota’s militia “for larger assaults”.
The added-value of the Antarian Rangers to Kota’s Militia is clearly intended in the case of “larger assaults”, which implies that Kota’s Militia would require the Rangers mostly for their combat and possibly intelligence abilities rather than their logistical support.
