The Helmsman Saga

The Helmsman Saga is a Space Opera series by Bill Baldwin. Essentially a WWII Recycled in Space, it tells the story of Wilf Ansor Brim, an officer from Carescria, a poor and despised province of the Galactic Empire, fighting his way through two galactic wars between his Empire and the League of Dark Stars.

Started in 1985, seven books have been released by 1996. Then, after 15 years (and several years of constant promises), the eighth book was released in December 2011.

Tropes used in The Helmsman Saga include:

All There in the Manual: There is a glossary and list of units on the Author's website (the former currently needs a bit of work).
Arms Dealer: Lixor is an entire planet.
Arranged Marriage: Margot and Rogan LaKarn. It doesn't work out.
Assassin Outclassin': An interesting case. An assassin sent to kill Wilf cannot carry out the job because she owes him a life debt, and he accumulates new ones faster than she can repay. And the assassin's code demands that if she can't kill him, she must kill the one who ordered the hit. She does.
Bavarian Fire Drill: In the first book, Wilf is among a team captured by a League ship. He escapes, manages to kill an officer and steal his clothes. Then he uses his supposed rank to get into the engine room and disable the reactor. He's pretty far along by the time anyone starts suspecting.
Better to Die Than Be Killed: In The Defenders, Wilf is stranded on a League planet along with three people. One of them is the Emperor. He states right away that Emperors cannot fall captive, and makes the others swear they'll kill him first.
BFG: The Hador-Haelic space forts have guns which are hundreds of feet long.
Call a Rabbit a Smeerp: All the time. Alien pigeons, cats, horses...
Chekhov's Skill: Wilf knowledge of the League language is used a lot.
Cultured Warrior: Wilf knows a lot of poetry.
Dirty Coward: Puvis Amherst. And he leads an entire organization of these.
Earth All Along: The first books seem to imply the series are set in distant future, but Turning Tide has Wilf's escape pod land on Earth in December 1965.
ET Gave Us Wi-Fi: At least three races were given the final push toward interstellar travel by interstellar Escape Pods. In the eighth book, a pod is left on Earth - deliberately.
Everything's Worse with Bears: the Expy of Russia is inhabited with large bipedal bears.
False-Flag Operation: The League captures a Fluvannian cruiser and use it to attack one of their liners.
Fantastic Drug: Timeweed.
Fantastic Racism: The League hunts the Bears for their pelts. Wilf himself deals with it a lot in the Empire because of his birthplace - although it gets better over time.
First Girl Wins: Not quite certain yet, but she does tend to reappear all the time.
Forgotten Superweapon: The Hador-Haelic space forts. They are remembered, actually, and still in pristine condition after thousands of years... it's just that no one remembers how to power the guns up.
General Failure: Megan Trafford.
Genius Ditz: Covall the Wraith.
Government Drug Enforcement: All of the League State Sec are addicted to timeweed from childhood.
Honey Trap: The Trophy and The Mercenaries each have a case. The first time, Wilf is warned, the second time, it's a bit worse.
I Can't Dance: Wilf has a lot of problem with that.
Insurance Fraud: In The Turning Tide.
Invisibility Cloak: Bender ships.
I Owe You My Life: The Turning Tide.
Long Runner Tech Marches On: In The Turning Tide, Wilf carries a cellphone and sends SMS messages.
No Biochemical Barriers: Averted. At least, emergency rations state which races they are good for.
Really Gets Around: After book 7, Wilf has a lot of one night stands - nothing to do.
Recycled in Space: Up to Eleven.
Rewarded as a Traitor Deserves: The League collaborators on A'zurn are executed as soon as the League takes over. Can't be trusted.
Rock Beats Laser: An interesting example in the Galactic Convoy. A city constantly suffers from airstrikes which no one sees. Now, it is known that the League has invisible ships, but no one understands how they make their weapon fire invisible. It's not until Brim actually sees it that they realize that the Leaguers are simply dropping bombs.
Royals Who Actually Do Something: Margot and Onrad.
Shoot the Hostage: Well, not shooting, but threatening to shoot works nicely on the League, because they believe Brim when he says the hostage will be executed anyway for failure and they only need to recover the expensive equipment.
Shout-Out: Captain Verger Antillies, a space station which must be taken out by a torpedo attack which gets right to the reactor, a planet named Throon...
Standard Sci-Fi Fleet: No fighters, Battlestars or carriers (at least yet), but everything else seems to be present.
Superweapon Surprise: The Hador-Haelic space forts activate right in the middle of a major combat.
Tank Goodness: The series are mostly space-based, but books 1 and 6 contain a bit of tank fighting.
Telepathic Spacemen: Nadia Tissuard. And a lot of people on her planet.
The Empire: The League.
The Federation: The Galactic Empire.
This Is Reality: In book one, Wilf Brim has a last stand against three League ships, and muses that Big Damn Heroes only arrive in time in books.
Those Wacky Nazis: The League.
We Will Have Perfect Health in the Future: At least parasitic diseases have been exterminated.
Winged Humanoids: A'zurnians. The Leaguers break the wings in half - roofed concentration camps are too expensive.
You Are in Command Now: In the first book, Brim has to do it all the time. Either the commander has been captured, a Dirty Coward, or away overseeing some trade negotiations (those are three different commanders).
