A sense of the progress of your side in a combat zone could be conveyed via a few audio callouts from NPC ships on your side.
"Woohaa! Another one down!" - This style of message, in a positive tone, indicates your side winning.
"Somebody help... I... I can't shake this bogey!" (goes to garbled static) - And from a negative perspective, indicates your side overall losing.
And it adds some atmospheric realism. On the flip side, any NPC vocals can quickly become repetitive.
