• There are more other races/animals fightin' together with the greenskin. Giants, Wolves, Boars, Squigs, Trolls, Wyverns, Snotlings and Spiders. It's cool to see Orcs live and fight with other races/animals in harmony!

• Goblins are more dominant in WFB, as they have more unit type, an elite Night Goblin type, better weapons and classes, Snotlings and a few Goblin HQs. I'd love to use Skarsnik, Lord of the Eight Peaks & Gobbla to eat up some enemy units! Good news for goblin/gretchin fans I suppose, since they are competitive to field some of them and you'll see them more often in WFB rather than in WH40k.

• There are much more miniatures available on the market today for Orcs and Goblins for WFB compared to Orks for WH40k.

• The Orc Warboss (which is suppose to be the most important unit in both races!) is available on a customizable plastic kit, unlike the Ork Warboss models which are not customizable unless you do some cutting, adding plasticard and greenstuffing. Plus, Warboss on Wyverns are cooler than Warboss on Bikes, especially Azhag the Slaugtherer...reminds me of Jake Sulley riding Wyverns in Avatar.

• There are more races in WFB for the greenskins to bash (15 main races in WFB compared to 12 main in WH40k). There are stunties (Dwarfs) to fight wif which doesn't exist in WH40k.

• One word : DAKKA DAKKA DAKKA DAKKA DAKKA DAKKA DAKKA! Ok thats seven...

• Looting and kitbashing! There are tons of Ork players out there making their own Flash Gitz, Looted Tanks, Battlewagons, Gunz, etc. Anything can be looted and can be Orkified proppa by the Mekboyz! Plus you can make Orks wear any kind of freeboota clothings like pirates cause in Space anything is possible.

• Orks can use bits and parts from WFB Orcs with some proppa paint and some modification as a Feral/Snake Bite type of Orks, where as Orcs have a little bit difficulty in doing so because of the technological difference.

• Orks are generally bigger in size, in all aspects. The 40k Warboss is bigger than a WFB Warboss even without the Mega-Armor, Nobz are bigger than Black Orcs, and Orks have big vehicles (prolly bigger then many other races in WH40k as well!).

• Red paints in WH40k makes things go fasta, and the goblins in WFB failed to realize it. They should paint their chariots and animals red.

• There are more variety of weapons in the Orks armory. More ways to chop, smash, fry your enemy and MORE DAKKA DAKKA DAKKA DAKKA

• Battlewagon with Deffrolla. Orcs and Orks both like big things; and they should make a big vehikle in WFB that can roll/smash over puny enemies who dare to mess with the greenskins. The Empire already has their Steam Tank and I hope in the future that Orcs and Goblins have their own big 'un as well.

•  My personal opinion, Orks have more funny and memorable quotes over Orcs. :)

Orc and Goblin Cave Squig Herd

Squigs are weird beasties - part fungus, part flesh, but mostly teeth and claws. Although they are wild and dangerous creatures, it is possible to herd them towards the enemy by means of pitchforks, firebrands and the beating of loud drums.

Retail Price : USD19.75 / GBP 12.00

You may need these metal blister squids for a few reasons, as Tankbusta Squig variant, Attack Squig for your Warboss, as a Angry Squig model if you successfuly turn a enemy IC using Old Zogworth's power, to accompany your Grotz and Runtherd, or simply stick it to your Ork vehicles for decoration purpose. Orks are a fun race, and squigs just add more flava into it. :D

• Know the Rule : Read the rulebook thoroughly, know the rules of running, consolidation, leadership checks, pinning, etc. If you're new and can't remember everything, you can jot down notes, print out the WH40k resources I posted on the Waaagh Resources and Tactica section, or put bookmarks on your 5th ed rulebook/codex to save time. Time is important ya know! :P 
 

• Know the Objective : Sometimes you don't need to kill everything to win. Know what it is needed to win the game such as, capturing objectives, scoring points, etc. Killing everything may sound fun, but it isn't fun to know that you lose if you kill more stuff than your opponent did and still lose the game.
 

• Know your Units : Know what you are fielding (duh) and get the most of the wargears you equip them with. Access their strength and weaknesses. There is no such thing as a "god" unit that beats everything to a pulp. Every unit,whether it is solo, big or small has a counter/weakness in it. Orks maybe good melee fighters, but there are bigger, more expensive units that will best Orks in hand to hand (mostly SM and Chaos SM). We live by numbers, and a nob with a Power Klaw and dats a fact! Waaaaggghhh!

• Know your Enemy Units : Either read about them before facing them, or ask the player if you're not sure...especially psychic powers cause they may swing into the favour of your enemy. e.g : Space Wolf Rune Priest's Jaws of the World Wolf, etc. It doesn't matter whether its his strongest unit or weakest unit, to know more is to get a better idea of what you're facing. Hatch a plan and do something first about the bigger threat to your current army and leave the ones with lesser threat later . It's also a bonus if you know the synergy of your opponent's squad and how he plays them (different people play play the exact same squad differently): aggresive, passive, offensive, defensive, etc. You'll find it easier and get a confident boost if you know what your enemy units are capable of and what they suck at.
 

• Know the Map : You need to discuss and decide with your opponent about the various terrains and covers before playing, e.g which terrain gives +4, which cover does not, etc. Deploy in the right cover spot according to your enemies deployment. It is always a tactical advantage to deploy last. A bad deployment may cause you lose the game. You need to know how much can the terrain block line of sight, and how many boyz can get that cover save.
 

• Know your Plan B : Yes, your opponent may have lady luck on his/her side and get lucky potshots killing off your tough and important units in turn 1 or 2. You may roll loads of 1 and get pissed off. Make at least 3/4 of your army capable of doing some damage on its own as a plan B. If all else fails, try to put up a fight before you go down!
 

• Know your Inches : You don't need to get the exact measurement, but just a rough idea will do. Movement inches, weapon inches, and 6" of running into assault. It is VERY important to know the latter as most Orks will need to assault into battle. Newbies may miscalculated the 6" and get denied the Assault on that turn and get shot to bits the next turn. Remember to run and not shoot if the opponent is just barely 6" away, as he may remove that unit as a casualty to deny you the assault. Roughly knowing your weapons range is also good so you don't screw up by unable to shoot and exposing your unit out in the open or its side/rear armor.
