Neither man or womans is great. The womans voice is especially sci fi/disney/cortana/siri for the setting of the game. It completely detracts from the era hearing the overly produced "Objective lost" of each.
Instead, it would be awesome to have adaptive narrative. It could be given the voice of someone of each nation in the game. Not some fake stereotype Russian or German voice. Hire some proper voices from each country and make a bit of effort with the audio so it doesn't suck you out of the illusion every time you take an objective. It could say things like "Objective A is lost but the fight's not over yet" or "Objective B was an easy victory, no doubt there will be more resistance as we push on" if the flag objective was uncontested for example. It might also slip in some sub conscious tips to people so they don't always sit way back and not play an objective like if someone doesn't hit an objective in 5 minutes then it could say "Get in the fight man! We need to push on!". Other games utilised this adaptive narrative really well and it would really add more immersion to the game from an audio perspective while helping newer players understand more about what's going on if done well.
