gameon: That would be tough! It's hard enough to lift someone, carrying them is another matter! 250 pounds is around 18 stone in english weight. Ridiculous amount.
While you can drop some of their gear should you need to move someone, even a moderate sized, healthy person with gear is going to weigh that much. 250 pounds isn't really a ridiculous requirement.
CthuluIsSpy: If she's suitable for combat and willing, then let her.
I do not understand the reluctance to let women fight, I really don't.
There's 2 reasons which aren't really anyone's fault but we don't know how to deal with them:
1) The physical requirements are quite high and 10 military men will be able to meet them for every military woman who will (guessing at the proportion but it will likely be something like this). Some worry this could lead to demand to reevaluate these requirements with too much pressure on removing or lightening them.
2) There are psychological implications, will men take risks under fire that they should not have because it's a woman by their side? This is part hard wired and part cultural. Survival as a species demands every single vagina possible, but only a few penises will do if things get bad. Yes, we're long beyond that actual need as a species but nature hasn't really caught up. Wasn't the gal's name Jessica Lynch that we "rescued" (possibly anti-heroically) in Iraq? Would the same be done for a man? Dead sons are hard enough for the public to take in a war, but the US as a culture doesn't value male life in nearly as much (there's a lot on statistics of this regarding our media, etc.), but dead women might cause an absolute shitstorm.
I see why we're having the conversation, perhaps it's actually sad, the only reason it is a conversation is because of our glorification of war in the US.
