Dwarf Slayer Pirates, my favorite unit in the army
I started this collection back towards the end of 5th edition when the Dogs of War army book was released. At the time it was a great innovation, a selection of wacky units that could either be fielded as a complete army of mercenaries or added to normal armies to add more variety (although I won't deny it was open to some abuse). GW also continued to add more of the 'Regiments of Renown' in White Dwarf. I enjoyed fielding this army at tail end of the 5th edition period, but one thing that always bugged me slightly was the lack of 'generic' mercenaries, everything had to be special unit, almost always led by a hero.
Then came along 6th edition, and all the previous army books were thrown out in one go and the game radically reworked. A couple of PDF's were released with what ere supposed to be 'get you by' lists until the books were done. Dogs of War never got a new book and I'm stuck using those lists to this day, however, the lists aren't actually that bad.
Heroes and Wizards
Inevitably with such an old list Dogs of War sit low on the power curve, but there's a lot you can do with these flexible lists. They provide the best of both worlds, the 'Dogs of War' list is a generic list featuring normal unnamed regiments, such as heavy cavalry, light cavalry, dwarfs, marauders, pikemen, crossbowmen etc. Then you have the 'Regiments of Renown' list which features all the special regiments from the previous book and White Dwarf, and you can use these regiments in an army based on Dogs of War list. It's good because you can theme a Dogs of War army however you like, but still add the wacky (and sometimes powerful) Regiments of Renown.
One of the 6th ed changes was to take the Halfling Hotpot out of the Empire army and put it into the Dogs of War army
5th edition; when two giants and a wizard was a suitable regiment
When being used this army is often joined by Dwarfs from my Dwarf army, Marauders from my Chaos army and any cavalry I can lay my hands on to represent light cavalry in particular, but occasionally some heavy cavalry can add a little punch.
