One of the issues I have with the BECMI treatment is that it doesn't do that. It overvalues training and equipment of typical humanoid soldiers, and undervalues the raw monstrous power of monstrous opponents. Some good gear and training shouldn't make a normal human with an average of 3.5 hit points a superior combatant to a hulking hill giant. Whether battles were run with standard D&D combat, at the tactical scale, or as a strategic abstraction with a couple rolls, I want it to produce very similar results.</p><p>2) The tactical scale needs to be designed to balance setting consistency with large units. For example, I would like it if each unit were 100 (or even more) Medium creatures. But I also need to allow for units of other sizes, that can properly face off against a unit of Medium creatures. It seems a bit absurd to have units with multiple Gargantuan creatures, so that limits the maximum size of my units. Each unit needs to be appropriate to pair off against a single Gargantuan creature. By appropriate, I mean that tough creatures should still feel tough. So if you've got a unit of typical baseline Medium troops (maybe the guard statblock with a special trait for their unit type) a unit of Large ogres, or Huge giants, or a Gargantuan anything should destroy them. It should take at least 2 or 3 units in succession, a PC or powerful NPC led unit, or a group of more elite troops to defeat such a threat. At the same time, the numbers of creatures in such other units should make sense in the world, and on the battle field as far as dimensions. 50 ogres isn't believable. Half a dozen is. 12 is maybe/iffy/depends on how well all the other moving parts fit. So the different numbers of Medium (or Small), Large, Huge, and Gargantuan (should be 1) combatants that should be the standard for a unit needs to be devised to give good results, where monsters feel scary but don't congregate in unreasonable numbers.</p><p>3) There should be a few different basic troop types (heavy infantry, light infantry, heavy cavalry, light cavalry, etc), but it would be nice if I can avoid having to mess with stats for most of the monsters. So maybe hobgoblins could just be set up in a heavy infantry melee unit by choosing to use their shield and sword, or a ranged unit by putting away their shield and using their bow. When it comes to using the stock NPC stat blocks, the average soldier would probably use the guard stats (seems standard in 5e), but the different unit types could make slight changes to gear and provide unique features based on race (maybe elves get Advantage on ranged attacks and ignore half and three-quarters cover, so that hobgoblins don't totally own archer supremacy by virtue of their Martial Advantage). Probably worth having the troop types give the guard statblock a bit of boost as well as the race to get it to CR 1/4. It just seems like a typical soldier should be able to take on a typical goblin warrior. The soldier statblock from the Ravnica book might be a good pattern for elite heavy infantry, but making it standard just throws stuff off by being a bit too good.</p><p>4) There should tactics, but they should be simple. I probably don't want a dozen different types of formations, but I would want a few. For example, maybe infantry have standard, defensive, and aggressive. Flavor as desired. Or maybe they need a few more for it to cover everything that needs covered. (We're at the broad strokes level here.) Units are being controlled as a unit, not as individual members, so the exact way the individual troops would be configured isn't going to make a difference. If miniatures were used, one miniature would equal one unit, not one troop.</p><p>5) Morale and winning by routing like real battles should be a thing rather than everyone fighting to the death, but since some creatures are immune to morale concerns (an army of mindless undead, for instance), the rules also need to be able to run battles that destroy units to the last creature.</p><p></p><p>Some thoughts I've been having include:</p><p>-Powerful leaders and bigger creatures could perhaps be accommodated by having some sort of simple rule for a mixed creature unit. So maybe a standard unit needs 4 Huge creatures, but a Huge mixed unit might have 2 Huge creatures and X Medium or X Large creatures. So maybe you have 2 frost giants as half of the unit and a bunch of orcs as the rest most of the time to get a more believable unit. And maybe the same thing happens with a PC/NPC led unit, where they count as "half" of the unit (even if it's assumed that there are actually a couple dozen troops or so as their personal guard so they don't throw off the dynamics). If there was only one frost giant that was a leader of the orcs, they could also count as half of the mixed unit, and it's assumed there are extra orcs (and/or generic whatever troops) as part of their half.</p><p>-There needs to be some way to take account of the fact that a well-placed <em>fireball</em> can probably take out most of a unit, without running it in actual 6 second rounds. I'm not sure what the length of tactical rounds should be. There also needs to be some way of handling the fact that if you <em>don't</em> run it in 6 second rounds you could cast all your mass damage spells in one or two longer tactical rounds, and a dragon could be using their breath perhaps even more than once per tactical round. It's less of a concern with spellcasters. You might even go so far as to say you can just straight up cast as many spells as you have slots for. Throw out 8 <em>fireballs</em>, and annihilate the nearby units on your turn. Then you're out. Wouldn't work so well with a dragon's recharging breath though.</p><p>-Needs to be some way of handling powerful solo creatures that aren't Gargantuan. For many, they could just be a mixed unit with other troops, but for flyers, like a Huge dragon, for instance, that doesn't work. Some high level PCs could also solo a unit or two of troops without any help before going down. That could be run as a normal fight though, whereas you wouldn't want to zoom in the battle to regular D&D creature combat rules just because the dragon involved is Huge instead of Gargantuan.</p><p>-There needs to be some way to determine how to deal with transitioning different scales. So let's say your high level fighters unit gets destroyed, but he survives and wants to go try to get to the enemy commander (who still has some of his unit left). There should probably be a way to pause the larger battle and go to standard D&D rules to run it. This also ties into how the more zoomed in scales can affect the larger ones. After doing that, you might go back to the tactical scale, and lets say you're only running part of the overall battle this way, so after you finish it up, then you take the results and plug them into the abstract "War Machine" kind of rules to see how the overall battle turns out after accounting for the results of the parts you played out in more detail.</p><p>-The various formations and troop types should all take up the same space on the tactical field, and the various pros and cons of formations and troop types should be represented by standard 5e things like Advantage/Disadvantage, reduced movement, cover rules, etc. While close formations would realistically pack more troops into the same space, I think it would make them <em>too</em> good to actually say two or three of them can fight against a single loose formation unit. It would also undesireably penalize forces like a typical horde of orcs who are all going to be in an irregular formation but should still be powerful. That being said, these sorts of differences should be meaningful. If you played out troop movement in standard D&D with everyone packed together in adjacent 5' squares, they would end up moving slower than normal due to difficult terrain unless it was a completely flat field; if the individuals were spaced out with an empty 5' square between them, they wouldn't be slowed down as much because they could better maneuver around difficult terrain. So it makes perfect sense and sticks to thing #1 I want to say that in the tactical warfare scale close combat formations have reduced movement. Maybe a close defensive formation gives everyone three quarters cover instead of the normal shield bonus, but each space of movement costs 3 movement instead of 1. That sort of thing.</p><p>-Hit points of units should probably just be the combined total of the troops in the unit. Damage of a unit should be the combined average damage total of all of the attacks of an individual creature, times the number creatures that can be brought to bear. The standard unit rules would determine this most of the time. So if the rule ended up being that a Medium unit is about 50 troops, with 4 ranks of 12 troops, then the damage for typical guards (4 damage average) is 48, since 12 troops can attack at once. Maybe for ogres it's 12 in a unit, and 6 of them can attack at once ( or 8 in a unit and 4 can attack at once, or however it works out). I'm not at all sure how to make that fit with things like swarming around your foes, or even a loose melee where everyone wades into and no one is holding a formation. Most of those sorts of things should be dealt with by bonuses and penalties of some type, rather than changing the position of units on the map. On the map, they should each just take up a single space.</p><p>-One way of doing attacks might be that if you hit you do the full damage, and if you miss you do half damage. Crits might do double and 1s might mean you failed to do any damage. There could be better ways to do that. It's generally hard for one force to attack in melee without getting counterattacked during that attack, but I'm not sure what the rule should be for that.</p><p></p><p>As you can see, most of the thought has gone into the tactical scale, probably because that's harder to do. The abstract scale is a lot easier, because you can reduce the battle to a series of a rolls for each clash (just roll until one side retreats, gives up, or captures or destroyed). You just have to figure out how all the math works to match up properly. Probably things like good tactical choices could just provide certain modifiers to these rolls.

[QUOTE="Sword of Spirit, post: 8362104, member: 6677017"] WotC gave it 2 or 3 tries years ago in UA articles, but none of the attempts were quite good enough to make it to prime time. While I'd love to see them put out Birthright and include mass combat and domain management rules, I would be mildly surprised if that happens any time soon. It could be one of the classic settings for next year, but probably not. In the mean time, my creativity has started flowing towards mass combat for some reason, and I want to see what I can come up with. I know there are 3PP mass combat systems, but I doubt any of them will do what I want it to do, for a couple of reasons. -Most of them are probably extensive affairs in largish books -Most of them probably don't "fit" 5e terribly well. I'm not really looking for a giant book on realm management and warfare that makes a lot of assumptions about the world and requires a lot of effort to use.
