Army ostriches.

Sir, our women, sorry, "female" soldiers are getting pregnant at a rate that exceeds combat casualties.

What should we do about it?

Well, sir, since these pregnancies do cause us manpower shortages at great expense, violate military regulations, put a burden on our limited resources that could be better spent winning the war, that the women don't contribute anything intrinsically to combat operations, that they detract from the war effort by their effect on morale and, of course, there is the moral objection, perhaps we should remove them from the combat zone.

We can't do that!

Why not, sir.

Because...

Yes, sir?

Oh, dash it all, I don't know. Tell them to use condoms and hope it all goes away.

Very good, sir.
