Drackalicious jumps into a controls seat and since he has never used this system before... Basically begins hitting random things with appropriate names. Some weird noises happen and it looks like the system might actually crash until he is literally shoved out of the way by Will who takes his seat while saying "Dude seriously, the computer illiterate need to not touch the military grade hardware ok? Leave it to the techs?" Will quickly gets to work (and spends a luck to boost his success to an extra success).
In moments the system around them announces. "Close combat Smoke Screen Training. Do not enter the field while adaption is active." The room instantly begins to change, cover appearing out of the ground, walls and floor to form a labyrinth, one all cadets are very familiar with, first years spend weeks in this set-up training. As things change the previously beleaguered marines wave at a camera, Only Nina recognizes the signal however as "provide distraction" the other thinking they just waved their thanks.
The team in the Sim room see the Marines put their training to use, they know the layout and where holographic and board target will pop out but the Covenant don't so while the Marine's take up field dominating positions, the covenant are entirely flat footed, smoke suddenly pumping in from seemingly random vents in the floor only makes things worse for the Aliens, only the Elite appears to have any idea what is happening.
Will stands up again. "Right, that scenario will run for half an hour on auto now, and I'd bet my life on the marines winning, they have a mix of weaponry down there and they know everything that will happen." He grins at the others, clearly wanting praise, kind of like a puppy.
