Okay, so I'm no veteran to Dwarf Fortress. I've probably been playing for 6 months now and have made about 15 fortresses total.
Needless to say, the defense of my fortresses almost entirely exists off of cage traps, and I want to fix that.
I have 4 squads now. My best one so far is an axeman squad which has been training for about 4 years now, but the best soldier is merely adept while the majority of others are novices or adequate. So why are they taking so long to train? I have them train year round, 10 out 10 at a time, and they are just barely becoming axeman. How come? They're all suited in full masterwork steel armor and weaponry, but are progressing like slugs. What's the best schedule setup for effective training? Would it be detrimental to have, say, 2 spearmen, 3 hammermen, and 5 axemen in a squad, since they would train each other in skills that they aren't going to use?
What are the different perks of each weapon type?
Axes - Close quarters combat, hacking off limbs.
That's as far as my weapon knowledge goes.
What's a good way to crosstrain soldiers and how long does crosstraining take? It seems like having soldiers operate screw pumps or smooth walls on their off time are the best options, but how long do they need to do this to see results?
I have my dwarves execute disarmed invaders, but they don't get too much skill from it. I'm afraid of them doing it with training weapons however, because it would be a shame to train a dwarf all the way up, only to have him become attached to the wooden axe he so mercilessly smacked goblins with.
How effective are ballistae? Is training some dwarves up to legendary siege operators by having them fire catapults all day actually worth the loss in hauling potential? Also, what's a good setup so that the ballistae actually get a chance to fire on invaders and not get scared away too soon?
How effective are crossbows? I've yet to employ marksmen into my military, so I don't know how well they work.
What's the best way to hold back the evils of the caverns below? Have a barracks between the entrance to the cavern and your stairway?
How can you employ magma and water as methods of defense for your fortress? Could someone explain to me and the other Dabbling Dwarf Fortressers[V. Rusty] the intricacies of the almighty pressure plate?
What, in general, is the best fortress layout, in terms of above ground defenses? All I have is a 3z high wall surrounding my stairway to the fortress. There are 2 entrances, 3 wide each with cage traps and drawbridges defending each. My barracks are also out there.
That's it as far as my questions for the military go and typing them out has made me realize how many questions I have about the other aspects of your guys' fortresses. I'll save those for another topic.
Please share any knowledge you have on any of the preceding points. (Or knowledge on any other part of fortress defense that's been unmentioned thus far)
