Next is an underrated series from the early 2000s, it's Pumpkin Scissors.

In alternative Europe, war has come to an end but the Post War Period is jammed full of poverty and former soldiers turned bandits unable to give up the fighting. Step forward aristocrat 2nd Lieutenant Alice Malvin, Field leader for Imperial Army State Section III, specializing in War Relief to beat the bad guys and give everyone rousing speeches just because she can.
Joining Alice is the spectacle wearing Martis and lady killer Oreldo, while at base issuing the missions is old man Captain Hunks; a 12 year old girl who's not really 12, Stecchin to serve the tea and messenger dog Mercury who likes biting people.
All is normal until they are joined by a walking giant of a man named Randel Oland, who is a former anti tank trooper, with powerful anti tank handgun and a seemingly invincible body as he ignores pain and fear to take down his enemies with the help of a Blue Lantern, in fact they were so terrifying in battle that they were referred to as "Gespenster Jäger" which is Ghost Hunter in German. Not the only German phrase you'll hear in this series, "Toten Sie" gets mentioned a lot which means "Kill Them" in German.
I will be blunt with this one, it's Full Metal Alchemist set in World War II minus the Alchemy, but it's not a criticism, far from it, along with the Gundam franchise it's one of the few shows that's good at portraying how terrible war is and how cruel certain people in power are, it's also one of the few anime that genuinely seems terrifying in context, once that lantern goes off, Randel is terrifying to watch and it gets worst meeting up with other units similar to Randel's Anti Tank unit including a man from a Flamethrower unit.
It's not perfect though, it clearly hasn't been given enough episodes to finish the bigger story and the sad thing is that it ends in a Ballroom Blitz scene where Alice keeps changing her mind about what she's fighting for when people continue to contradict her during her speeches which eats up a lot of running time, not made any easier when you consider that 1. she's an Aristocrat, 2. The people involved are against the Aristocrats and 3. She can't be taken seriously wearing an evening dress. It's also pretty poor at timing it's comedy as a deadly serious episode loses effectiveness when the ending theme is rather jolly. Also I'm no expert on recruiting but Stecchin clearly shouldn't be in this anime, she looks like she belongs in a moe military series, yes that's a genre now.
Some of those are nit picks and I can't really complain about it's production values or dubbing as everything is top notch.
Final Verdict: It's very underrated and needs more support than it currently gets, definitely worth a watch.
