Affirmative, Commander.
Carefully search throughout the hospital and take along to the shuttle all the useable medical supplies and medical equipment. If, by some miracle, there are any relatively uninjured survivors - shoo them away from the base; take any and all remaining survivors, as well as all the mostly intact heads of the dead, to the shuttle.
Check up with the team for the heavily injured and head-intact bodies elsewhere around the place, and get them all to the shuttle as well.
Addendum, if I may, Commander: if anyone sees a less-thoroughly killed human around the base - and by that I mean a body that is still sort of living, or has a more or less intact head, either take them to the shuttle or notify us so we can grab it ourselves. No futile and useless deaths on my watch.
Request additional shuttle runs if all of the above does not fit in one. Survivors first, medical supplies and equipment next, and finally the heads. Remain planetside and leave on the last one.
...And what if they decide to detonate anyway? - It's not like I expect to live through the next 24 hours, anyway.
And then, I trust in General.
((Note to Piecewise: Yes, I wholly intend to get this ridiculous amount of heads and other things and people back on board. No, I don't intend to hoard them for myself. We have a war to wage, and Maurice has responsibilities to the Movement. And ideas how to help the cause.
Also, just for everyone's convenience, would you mind abstracting the medical supplies - maybe to 'emergency kit refills' & 'advanced kit refills' & 'battlestimm doses', or something hammerspacey like that (maybe also adapted to reflect the stuff we could find here)?))
