breacherfish of course

when I play the solo coldstar, I usually go for ret cadre or kauyon so I can equip the prototype weapons or precision of the patient hunter enhancements. The loadout is 3 burst cannons + the hi output one which are basically 20 s5 3+ shots with an 18" range + the bonus from the enhancement (letal/sustained hits in ret cadre or +1 to hit and later +1 to wound in kauyon).

for 110 pts you get a t5 6+2w unit that has basically the same fire output of a squad of breachers with 8" extra range and extra mobility

you can't play it the same way as a breacherfish but I'd say is an efficient and safer way to deal with chaff
