If they can meet the requirements, sure. BUT - they should not relax physical requirements to let more women into front-line combat. I have no doubt that women could pass the same physical tests as most men could, if they were given the incentive to do so.
Women can fight. During WWII, there were quite a few women soldiers (hundreds of thousands of them at the very least) fighting for the Russians. They went into some of the fiercest battles like the Battle of Kursk or the Battle of Berlin. The Russian women proved that women could drive tanks, use sniper rifles effectively, use AAA guns and perform admirably well as combat medics. There are too many stories of russian women running onto fields, picking up wounded men and literally hauling them back to the field hospital for these stories to have been made up. Women are capable - but they're often told that they aren't.
Now, there are going to be some differences between men and women. I doubt most women will be able to attain the very peak physical fitness required for the special forces such as the SEALs or the British SAS. I'm sure some could... but women are, like it or not, on average, weaker physically than men. That's not to say that they are weak - and if a women exercised enough, a woman could be as strong or stronger than an average man - but when you start getting to the extremes of physical fitness, women don't reach quite the same level as the men do. Look at weightlifting in the Olympics - the women weightlifters are very strong - far stronger than the vast majority of men, but the male weightlifters can lift more than them. On average, men have more physical strength than women..... it's why women have been kicked around so much during history. We could hit them, they often couldn't hit back - and that was horrible. It still is horrible (it is still occurring).
But for your average soldiering duties, women can do what men do. They can load a rifle. They can aim. They can set up and use a Mortar. They can drive a tank, operate a radio, storm a building. The Russian women proved that they could do that stuff. I see no reason why other women from other nations couldn't. And if women want to kill, bleed and die for their country, they should be granted the opportunity. I know for a fact that many women in the US army desperately WANT to be on the front-line.
