I do not question Mr. Kennedy because I myself have no reason to. If you have similar concerns, then you should bring them up yourself. I am not your nursemaid. You are hopefully mature enough to ask your own questions.

But you wish for a scenario. Very well. A scenario, then:

You recieve report of an Ohm world having been located, teaming with billions of Ohm warriors. They are poised to strike at a world which the crew cannot reach in time. The only way to stop them is on their planet.

But facing them on their own world would be suicide. The only way to destroy them without sacrificing the entire crew is to send a group with a reaction-bomb into perhaps a noted fault line or a vein of unstable material in the ground. Regardless, this would have the effect of wiping out a vast majority, if not all, of the Ohm forces on the planet.

However, the group that must perform this task will most certainly not survive. The group would have to be large enough that its loss will most certainly impact the crew's ability to defend itself. No one among the crew wishes to go, but you have exhausted all other options.

I do hope that is specific enough for you. Now, which will you choose?
