I use them to help fill out my troop list, Little 5 man sqauds with a lascannons (which is much cheaper for tach sqaud as aposed to Dev, sqauds). Many times they end up being A 4 man sqaud when they pump up the DC. I try to make sure all 6 troop slots are filled with these and scout sqauds with PF. The DC is Deadly and can be fed by the black rage striking all of these units. Remmember sargents lose all there previous gear when they join the DC. But Vet sargents can be armed with a Free PF or PW when they join the DC. Therefore all my Sqauds at least have Vet sargs if nothing else. Nothing like swooping in with a 15 strong DC with 3 Pf, 3Pw and a decked out master chaplain. Theres not a HQ sqaud in the game that can withstand this. With free JP and the ignore injury rule, OUCH.
