One man lost his spine, the other has a broken heart, the third is disobeying all orders... Morale is going downhill fast.
Oh, I know! The best way to mend a broken heart is a woman's touch. Vanessa should be able to take care of that.
As for the lack of spine and disobedience, all I have to do is remember that film where I played the commissar. If I'm lucky, I won't end up getting killed by my own troops.
"You there!" Flint yelled, pointing at Yancy, doing his best to sound serious and scary. "The state of your uniform is a disgrace! Get that fixed, soldier!"
"And you! Trying to weasel your way out of doing your part for the mission, you coward?" he continued, this time pointing at Leonardo's corpse. "Quit slacking off! You die when I give you permission to die! Not sooner!"
"Vanessa, this is no time for naps! Get up this moment soldier! I trust you are capable enough to at least take care of the sorry state of those two while I handle more serious matters. And be sure to keep an eye on them. They might continue their insubordinate behaviour."
"As for you, Mr. Stabby-" he finally said, pointing at Anthony with his industrial mining laser "Your treasonous acts will not be tolerated in my army! You might be strong, but strength is no match for expertly wielded high energy weapons and several tons of angry metal! Stand down or I will make you stand down!"
Since he has increased strength, trying to trap him would not work. In fact, if I used a forcefield, it might cause more harm than good if it explodes.
Furthermore, his diminished intelligence and inability to navigate properly means there is no point in observing him to try and see what he does or trying to reason with him. We know the general direction he was headed towards and that's enough.
If I had magic I might had been able to do something, but I don't. So my best course of action is what the AM taught me: Decapitate the danger. Preserve the corpse. Protect your teammates. Sort it out later.
But just in case...
Kneel down (if that's a thing that helps with battlesuits and lasers) and wait for an opening as he breaks through to my side of the wall. We don't want friendly fire here and since Mr. Stabby is working on the goop wall, that should give me some time to take careful aim. Then, when I'm ready, off with his head! And his other limbs if he remains standing.
Edit: If the others attack first and it turns out he is invincible or something similar, then goop him good and yell at people to get to work getting us out of here. Edit2: If his suit is not invincible, then try to damage his helmet with my laser before gooping him. He might be invincible, but if I goop his mouth and nose he might choke to death.
