Hey, It's That Voice!: In Japanese, Zaka is voiced by Kazuya Nakai, also known for his role as Roronoa Zoro. And he's Steven Blum in English, so there's any number of reasons to squee for that.
Likewise, the Ohtsukas (aka Solid Snake and Big Boss) voice Jaeger and Gregor. Now if only Jaeger had got a giant Ragnite Payload Lance and went "I AM THE NIGHTMARE OF GALLIA". Also, Lelouch and Suzaku's Japanese VAs come back for another round (as Maximilian and Faldio, respectively). Not to mention... Maxmillian is almost like a 100% evil Emperor Lelouch.
It's hard not to think of Revy whenever Rosie finished a sentence with "-da ze" (which was often).
There's also how Cordelia is obviously voiced by Mamiko Noto in the way she used to voice Mercedes.
Irene Koller (the narrator) and Ms. Ellet (who turn out to be the same person) are voiced in English by Kari Wahlgren, the voice of Ashe from Final Fantasy XII and Raine Sage from Tales of Symphonia.
In fact, chances are anyone who's savvy about English voice actors will recognize quite a few of them. Among others, Welkin is Dave Wittenberg (Kakashi), Alicia is Colleen O'Shaughnessey (Sora, Genis, and KOS-MOS), Rosie is Hedy Burress (Yuna), Largo is Fred Tatasciore (The Hulk, Saren, and additional voices in everything), and Faldio is Robin Atkin Downes (Luxord and Travis Touchdown).
Dammit! Now I have the mental image of the sevens screwing up, and Faldio shouting "TEEEEEEEEAM!"
Gregor is voiced in English by Roger Jackson, who is perhaps best known for voicing Mojo Jojo from Powerpuff Girls, and the Phone Voice(s) from the Scream franchise.
Perhaps the strangest of all is that April Stewart, the voice of Selvaria Bles, is arguably best known for her voice talents for practically every female character in the series South Park, of all things!
Murdock decided to join Gallian politics as the prime minister, who began to play both the Federation and the Empire and was executed on the orders of Tunnel Rat as he does not want to work with a double crosser.
If you've played Ace Combat 5, you should know that Welkin already has some experience saving his nation's leader - from a much more dire situation, in fact. And managed to evade Mobius One's wrath a few times.
Alicia should consider bringing a shovel to the frontlines as a melee weapon.
The anime has the following trivia:
Fan Nickname: Faldio is often referred to as 'Superman' for his ability to do no wrong at certain points in the anime. Probably to make his eventual fall that much more shocking.
Maximilian has been called 'Maxi-pad' by people who are familliar with the game, due to the fact that he seems to be a mama's boy and well, just look at Lelouch's profile.
Early on, the series itself was nicknamed 'Kana Goes To War' on account of Alicia's various goofy facial expressions.
