Colonel Vorgath is the third boss of the new (as of patch 1.2) Operation, Explosive Conflict. This is the puzzle boss in Explosive Conflict, and is really cool in practice. Sweeping the mine field is fun for everyone involved, and the boss at the end is challenging without being impossible after the long process of getting to him. I have a video further down showing the tower view for those trying to solve the puzzle.
Group Composition:
- 2 Tanks
- 2 Healers
- 4 DPS
Alternatively you can do this with a single tank, but unless you're switching people between bosses you'll need 2 tanks to get here.
Attacks (Droid):
- Cleave
- Melee
Attacks (Vorgath):
- AOE Knockback
- Demo Round
- Marked Explosion
- Ranged
Mechanics:
- Sweep the mine field
- Disarm bombs to advance through the mine field
- Turrets will attack players the whole time they are in the mine field
- Vorgath will spawn 4 turrets that must be handled
- Vorgath will switch targets randomly
Story Mode Strategy:
One tank is responsible for sweeping the minefield and one tank will move with the group to handle the Demolition Droid that spawns and drops the bomb defusal kit. To begin this fight just approach the shield, it will disappear.
In the tower:
Click on the squares to uncover the bombs. We stayed with the middle two squares so we could pick the path of least resistance without having to uncover the whole field. Once the raid can not progress further (two red squares) click the button to the right and you will be teleported down (as a hologram) to the mine field. There will be a droid hovering over your head, it scans in a cone directly in front of you - the idea is to run around "sweeping" the mine field to uncover the demolition droid.
Once the droid is uncovered head back to the tower and sweep further ahead of the raid while they kill the droid. Once the droid dies mark a square to be disarmed (turns yellow).
At regular intervals a "strong" add will spawn in the tower that must be killed by the tank. In addition there is a cooldown after marking a square yellow - presumably to keep the person from disarming two mines with one kit.
In the field:
Adds will spawn constantly, there are three of them - normals only, they don't do much damage and can be killed easily.
Move ahead on to green squares and progress toward the other side of the mine field. DO NOT step on red squares, or squares that have not yet been marked.
Once the tank in the tower appears as a hologram get ready to kill the demolition droid that spawns. The tank should pick up the droid ASAP at this point. The droid does mostly normal melee attacks, but has a "cleave" that does respectable damage and should be interrupted as much as possible.
Once the droid is dead there will be a notice for the raid on who received the kit, that person will also have a wrench over their head (not sure if this is visible to others or not). The person with the kit needs to wait for a square to turn yellow, then run over and right click (interact) with the mine to disarm it.
NOTE: Only the person with the kit can move on to the yellow square, anyone else will blow up.
Once the group has made it to the far side of the field there is a control panel on the right side that will disable the turrets and disable the rest of the minefield.
From here the Colonel is just ahead with two adds. The tank should jump in to get aggro and let the rest of the group kill the adds quickly before focusing on the Colonel.
The Colonel has an AOE knockback that he likes to use regularly. He will also mark a random player with a red circle, that person needs to move away from the rest of the group until the bomb on them explodes. The circle is huge and hard to miss.
He will also swap to a random target at regular intervals, the tank needs to taunt back, but even doing that the other player will take some damage and needs to be shielded/healed through it.
At some point during the fight the Colonel will spawn four turrets (two on each side) these can be CC'd until the end, or quickly burned down. The enrage timer is tight and even CCing them we hit it, so it might be best to leave them until after - more testing will solidify this strategy.
Interrupt cleave on the droid as much as possible. Make sure to taunt the droid when it appears to get it over to you ASAP so the rest of the raid can focus on burning it down quickly. On Hard Mode interrupt Overload every time and you'll have to let someone else worry about cleave.
Watch for the target swap and taunt the Colonel right after it happens. Also watch out for the knockback and save your gap closer to get back in range quickly. If you stand too far away he'll drop a demo round on you while you're trying to walk back.
If you're OTing for this fight, watch the main tank - there can be some spiky damage, if necessary taunt off him, or help with taunting when Vorgath switches targets quickly. Pick up the turrets when they spawn to keep them off the rest of your group and the main tank.
Fun thing to try if your raid has a good sense of humor, take your time killing the first add and take your time uncovering the squares, the video below will show you the results. It's something to do at least once ;)

Hard Mode Strategy:
To begin we all ride the elevator up to the tower and kill the first elite that spawns, then one ranged DPS waits in the tower and uncovers more squares while our second tank sweeps the minefield for the first time. This lets us get a jump start on the best possible path.
The assassin droids that spawn here can become a problem if you let them get to their target. Normally they will just walk forward using ranged attacks, but if they reach their current target they will explode doing a good amount of damage. These guys need to be killed quickly, and if they get too close someone who isn't their target needs to get in their face and knock them back.
The Demolition droid has an added mechanic, in addition to his cleaving he will cast "Overload" which is an AOE knockback with a good range. If he gets one of these off your whole group will likely be cast in to various mines surrounding them and all die. This has happened to us a lot. There is a pattern, he will cast Overload -> Cleave -> Overload. So make sure you're ready to interrupt when the overload comes around. We designate the tank and melee DPS to take turns interrupting.
TIP: I have noticed that I am capable of interrupting every Overload, as a JG My kick has a short cooldown and is always ready. So I've started interrupting every time. This also helps if I get jumpy and click on a cleave my kick won't be ready so it isn't wasted.
If the droid enrages you will also need to interrupt the cleave, I got hit for 24k damage once from it. It's good if you can interrupt it all the time to make this easy on the healers, but if not the tank can eat a few of them without too much issue.
For Vorgath everyone should get close to the far tunnel doorway. Frequently the turrets that are shooting us through the Minefield don't disappear and stacking back there will get you out of range. you will also be out of range of the turrets that spawn while killing Vorgath.
For this part the tank in the tower takes over "tanking" duties to give the other tank a break. So usually that means I'm DPSing and Cyn is tanking. Vorgath still switches targets so you have to be on the ball for that. We don't kill the turrets in this phase, the enrage is too tight and any loss of DPS usually means Vorgath kills everyone.
TIP: For this phase when the turrets pop up I make sure they aggro on me, which usually means saber throw one, taunt the other. We're normally out of range of the back two so I don't worry about them as much. Then I just watch and make sure they're firing at me, when they aren't I swap targets and taunt again.

TL;DR Recap:
- One person stays in the tower to sweep the field
- Green squares are safe, red squares are death
- Sweep the mine field to uncover Demolition Droids and get disarm kits
- Mark squares yellow to disarm them
- Vorgath switches targets frequently, taunt him back quickly
