The Warhound (one of the smallest true Titans) is almost exactly the same size as the Acastus (the largest Knight we have a model for): https://minicompare.info/?warhound-titan=&acastus-knight-porphyrion=

In OP's example, that robot could be a HUUGE model that is "looking down at" the little model, but since there's an obscuring terrain piece between the two (and since neither model are on the terrain footprint) that huge model could NOT shoot at the little guy? And likewise, that little model could NOT shoot the big model? Does the TITANIC keyword change this interaction at all?

That's correct. It doesn't matter how big the shooting model is, or how small the terrain between is. Obscuring says that if every line of sight between the two models crosses over the obscuring terrain, those two models are not visible to each other.

The TITANIC keyword is mentioned four times in the core rules, and none of those mentions are in relation to the rules of visibility, so TITANIC does not change the visibility rules at all. (The four mentions are once in a Stratagem, preventing it from being used on TITANIC units, twice in the Action rules, letting TITANIC units shoot and be engaged while performing an Action, and once in the Super-Heavy Walker rules, which specify that Super Heavy Walkers can't walk over TITANIC units.)

And is there a specific rule(s) that answer my question about height differences between models and if/how that effects obscuring? Just so I can let my friends know.

The rule is Obscuring 13.10. Since there's no stipulation of height regarding the models or terrain involved, it applies in every situation. Obscuring terrain is effectively infinitely tall.

From a rules perspective, if I'm using the imperial guard models but just painted in Tau colours with Tau symbols is there anything stopping me using the imperial guard rulebook?

No. How your models are painted is completely irrelevant to the rules of the game.

And would this change it I used a fire warrior body with an imperial guard head to make the commander so they're in Tau uniform?

Almost definitely not. People only tend to get persnickity about conversions or proxies when said conversion or proxy could possibly be confusing as to what the model is supposed to represent or be equipped with. An officer with a Tau chestplate is still going to pretty clearly be a human officer.

The only mention in the terrain rules that refers to terrain needing to be more or less than 2" tall is in regards to non-INFANTRY/BEAST/SWARM models moving through dense terrain, where such models are allowed to do so if the terrain is less than 2" high.

As far as obscuring goes, the obscuring rule only requires a terrain area with a dense or light terrain feature, no size requirements, and the definitions of dense and light terrain only provide examples of what types of terrain those categories cover, again no size requirements.

OP stated they were considing anything within 1" of the physical barricade to be the terrain area, so they had an invisible footprint, but all the models are still outside of it.

Physical footprints do make things easier and clearer, but what OP was doing was fine. 11th's rules do seem to assume you're using some sort of footprint for all terrain, and don't really mesh with using a piece of terrain without one.

Hidden and obscuring are two different rules.

Hidden applies to INFANTRY/BEAST/SWARM models that are within a terrain area that has at least one dense terrain feature.

Obscuring applies to all models behind and not within a terrain feature that has at least one light or dense terrain feature.

Check out the rule sections 13.09 and 13.10 for all the details.

No. If a defined terrain area contains a light and/or dense terrain feature is counted as obscuring, and the obscuring rule says you cannot draw any line of sight fully through that area terrain. It doesn't matter how tall the piece of terrain or shooting/target models actually are. However, as soon as a model is touching the terrain area, it would go back to seeing and being seen based on the normal line of sight rules (silhouette). For that specific piece of obscuring terrain anyways.

could I feasibly find somewhere to trade patrols around or smth?

Not really because:

1) You are relying on someone buying a more expensive product and then wanting to get rid of that product in exchange for a cheaper product that they could have just purchased themselves. I'm not going to say the number of people out there this applies to is zero, but it's going to be small and hard to find, especially if you're looking for someone to have a specific faction.

2) Lots of people bought the Armageddon box or one of the new starters (all the starter set models are in the Armageddon box) and sold off the half they didn't care for. High supply means there is relatively low value for these models on the second hand market.

Just buy the Combat Patrol(s) you want, they're still reasonable deals (or wait to see if you luck out, and the faction you like gets a Christmas Battleforce, they'll be announced in the next few weeks, and they're about the same value as the starter sets).

Just buy the Combat Patrols you want. There's no rules in the Starter set that can't be gotten online for free. The only reason to buy the starter set is if you like at least one of the factions, because the box is a loss leader and it's one of the best cost per mini options out there. But if you don't actually want the minis, that goes right out the window.

Gundam Wing was one of the cornerstones in my entry to anime/manga, so it's certainly important to me. And I've enjoyed the more recent anime series as well.

In terms of kits, I've got more Zoids, but that's only due to the fact I kept the Takara Tomy/Hasbro kits from when I was a kid. My purchases since I got back into gunpla building are pretty equally split between Zoids, Gundam, Frame Arms, and the Koto Girls lines (Frame Arms Girls, Megami Device, Arcanadea).

Age of Sanguinious.

The LGS, who should be able to arrange a replacement through their GW contact.

However, if you took the picture to show your issue, I'm not seeing it, as your bases seem to be correct. 3x 75mm ovals for the Exodite riders, 3x 75mm ovals for the Squighog Boyz, and 1x 90mm oval for the Nob on Smasha Squig.

"Both" is also a completely valid option.

The game doesn't care about how your models are painted, it only cares that you don't include units with the IMPERIAL FISTS chapter keyword alongside units with the DARK ANGELS chapter keyword. And the only units with the IMPERIAL FISTS chapter keyword are their two named characters. (Well, Pedro Cantor has it too, but he's not really an Imperial Fists unit).

So as you buy and build and paint your army, you can buy the Dark Angels specific units, paint them as Dark Angels. And you can buy the Imperial Fists characters, and paint them as Imperial Fists. And you can buy the generic Space Marine units, and paint them green or yellow as you feel is appropriate, and there's absolutely no issue putting green and yellow models on the table together.

Eventually, you may find you have enough models to play just Dark Angels, or just Imperial Fists, and that's fine too.

Knights have a Detachment that allows them to take Skitarii and Tech Priests, but aside from that Ad Mech do not have a rule that allows them to be taken as allies.

You can take those units in your army by using the Imperial Agents rules. If you do this, you'll have to remember that your Deathwatch units will not have the Adeptus Astartes keyword, so your army rules and Stratagems are not going to work on your Deathwatch units.

The push fit models can be tricky to get to fit flush. Some people clip the pegs and just glue them normally. In the past I've used Tamiya Extra Thin Cement, which is a solvent, on the pegs of push fit models to give a little extra leeway in getting parts joined snugly.

Your Warlord can be any unit with the "Character" keyword, which is pretty much every unit that's sold as a single infantry model, plus a few others. Titus and Calgar are "Epic Heroes", essentially known actors in the lore, but every faction has a host of generic characters too. For Space Marines that's Captains, Librarians, Lieutenants, and so forth.

Every character provides a buff for the unit they join, or sometimes for units nearby, so depending on exactly what units you want to use in your army, there can be more "right" characters to add to your force, but you should also feel fine about taking a character, or any unit, just because you think they're cool. Outside of the top competitive tables in tournaments, having your army have nothing but the "best" units isn't super important. And of course, with a new Space Marine Codex on the horizon (to be released Sept in all likelihood) it's entirely possible what buffs each character provides, and what units they work well with will change.

I'd recommend downloading the 40K app, as it's got all the core rules, and it's the only official* source of the army building rules (in section 25). You can also use the Battle Forge to play around with building a list, it'll show you what units you can put in your army, point values, and what units are Characters. And if you weren't aware, GW has released a list of units that will not be in the next Codex.

To pre-empt the question of "What are Legends rules?", they are rules GW releases for units that are no longer in production, they aren't considered when GW does their regular balancing passes, and they usually aren't allowed during competitive events. Because of that, some players don't like using or facing Legends units, but lots of communities don't really mind having them in game.

(* There are also 3rd party resources that collate the rules and/or offer army builders. Wahapedia, New Recruit, WarOrgan, etc... These will show you unit and army rules, which you can't get from the 40K app without buying a Codex.)

I wouldn't assume that at all. The SM and CSM model ranges are in totally different places.

To get something similar I use Baneblade Brown, wash it all over with Agrax Earthshade, and then line highlight with Celestra Grey.

If you wanted a bit closer colour match, you could mix a bit of Celestra into the Baneblade to lighten it a bit I think, and maybe do some glazing to get better gradients than I've got.

True but they have final say on what games get made.

Not entirely correct. They have a final veto. If someone comes to them with a game idea they don't care for, the game does not get made.

But if there is a game idea that they would like to exist, but no developer approaches them to make it, that game also does not get made.

Answer about using Knights.

Only the Underseer gets buffed, because only the Underseer model has the Tech-Priest keyword.

Only the models actually in Engagement Range (2") get to attack.
