Well then, the advantage is that each Klone head comes with a helmet for convenient covering.
Anyway, here's the rest:

Ho-hum. The Space Marine splatters a Jerk's head as he roams the battlefield, searching for... what?

Meanwhile, the very same Nega-Spartan who destroyed the Longbow's leg comes back to slam the hatch on its pilot. Some of you will now be faced by a crisis; which to hate more, Nega-Blox or Peaches?

A Nega-Marine takes a potshot at the Space Marine. He is ignored.

Then Nega-Barney blows a shoulder pad off of the Space Marine's armor. He is noticed.

The awesome power of Nega Barney vs. the incapacity for failure of the Space Marine. Who will emerge victorious?

Meanwhile, S'Lark charges into the fight. I forgot to mention that the last mercenary was also hit by Kate's attack, but the shot failed to penetrate his armor and he is just knocked sprawling.

S'Lark fires off an explosive stabsphere, blowing the Mediator to pieces.

As Tomtom is brutally blugeoned in a sensitive region of his anatomy, some sixth sense warns Ray of impending danger and he throws himself flat, narrowly avoiding the dagger that streaks through the space occupied only seconds ago by his head.

The culprit moves forward to finish the job.

Meanwhile, the pirates' deployment is halted as those at the front of the crew try to get at the wounded Tomtom.

"Haha! It's working! Onward!"

The pilot of the Impervious is not nearly so lucky.

Kate uses a heroic feat, leaping to the top of the Subjugator...

...rebounding off of Tomtom...

...and landing directly in front of the main body of Pirates, sending a few shipmates sprawling. It should be noted that this feat was a critical success. Well, actually about three critical success rolls in a row, so yeah...

Kate opens fire, and pirates die.

The Subjugator's gatling gun makes mincemeat...

...out of the revived Krawler's inhabitants.

Tossing one of his blasters aside, Ray uses the other one to finish a downed pirate as he draws his katana.

Dropping his Power Sword, the Space Marine grabs the Nega-Marine and throws him bodily at Nega-Barney.

His aim is good.

With Nega-Barney occupied for a little while, the Space Marine heads to the ruins of the once-mighty Trampler. What could he be up to?

Oh. That can't be good.

Agh, blurry pic. The last remaining Nega Spartan finds a Double-Bolter on the battlefield. Posing again, he assesses the situation.

A nearby Jerk finally manages to pull it together and gets to his feet.

Meanwhile, this pirate isn't about to give up on Tomtom. He charges, but his club strike is parried by the Kommando's chainsword.

Pirates attack Kate from all directions. A cutlass strike is parried by her warsaw, but she takes a hit from a Pirate's FlintBlaster. Luckily, her armor absorbs the shot.

S'Lark strikes at the Subjugator, shearing off the deadly gatling gun.

Tossing the Nega-Marine aside, Nega-Barney strides towards the newly repaired Space Marine, howling for blood.

Poor guy. The Speeder Kommando only just managed to sit up before he was gunned down by the last mercenary.

The Subjugator turns and opens fire with all weapons. S'Lark is massacred in the hail of projectiles and energy bolts.

The two ninjas engage, quickly becoming entangled.

Kate wastes no time in downing her former boyfriend, along with his lackeys.

The battle quickly turns into a mop-up.

Nega-Barney meets an ignominous end.

The Thunderclap is returning? As it soars back onto the battlefield, a transmission is sent out from Legavan HQ. "S'Lark is defeated, primary objective complete. Execute Order 62, and exterminate all Yellows in the area."

These two decide to hightail it outta here. The driver especially didn't like the sound of that last order.

The last remaining Jerk Officer attempts to beat a Kommando to death with his binoculars.

Throwing the tangled nunchucks and katana aside, the Ninja in black spears himself a Kommando.

In a desperate bid, the last Mercenary rockets towards the Subjugator.

Oh, the binocular attack failed, btw. Jett II jumps out of the Impervious' cockpit and re-arms himself.

Jett I takes a shot at the flying mercenary, but misses.

Hm? What's the Subjugator aiming at?

Oh. Looks like a Yellow in the Mediator's cockpit...

Ouch.

Tomtom hobbles to the offensive. Too far away to reach Kate with his chainsword, he hacks off the barrel of her gun instead.

The dropship rotates, dropping Elite Kommandos out of its hold.

As you can see, their weaponry has been upgraded somewhat, except for Slice's ion cannon.

Who's this? An elite Yellow Hunter of the Empire. In short, a professional racist.

0.o
The last mercenary hacks away the Subjugator's cockpit with his Nova Sword and begins to root around with his rifle.

With the pilot's head mounted on his gun, the bounty hunter charges off.

Krazed Kate beats Tomtom to death with what's left of her gun.

The Space Marine has dropped his Power Sword again... what's he after?

0.o This can't end well.

The smoking hulk of the Tigerhawk is sent for a final flight...

*wince*

With that, the Thunderclap is down. Kommandos bail in every direction.

Slice kicks the bucket, crushed under the Thunderclap's bulk. Curse blurry pictures!

Kate has commandeered Tomtom's chainsword and a blaster pistol. She leaps to the top of the Impervious just in time to see the Ninja decapitate Clank. They are joined by the mercenary.

Kommandos forward!

The Elite Kommandos get to their feet. Ghost readies his coilgun...

He takes careful aim.

Hm? Looks like Kate didn't beat Tomtom quite to death. He staggers upright.

Just in time to suffer the consequences of Ghost's critical failure.

The Space Marine hefts the fallen Trampler's Magnapulse rifle.

One shot, and little remains of the Yellow Hunter.

What's Kate up to this time?

Oh. That takes care of the last three Kommandos from the original drop.

Time for a satisfied smirk.

The mercenary and Ninja head towards the Elite Kommandos.

While the Space Marine readies the Magnapulse rifle for another shot.

The Elite Kommandos decide that discretion is the better part of valor and hightail it outta there.

Perhaps the only Yellows still alive within the Empire's borders, four allies of necessity are ready to get revenge (well, in the Space Marine's case, he just wants to kill something, and this seems like the best way to do it).
I had a lot of fun with this one. I don't care what anyone says, Nega-Blox make nice cannon fodder.
