Korea's army of senior citizens ready for battle. 'I don't remember the rifles being so heavy'

Article here. I have another idea: draft women. Or is that too nutty an idea even if the US armed forces insists women make even better soldiers than men? Excerpt:

'Excluding the two women in the group, most of these retirees or near-retirees had undergone South Korea’s compulsory military service in their youth. But the decades of rust were showing.

With the Senior Army assembled behind him in military formation, co-founder Choi Young-jin, a 62-year-old university politics professor, recited the group’s oath:

But South Korea’s fertility crisis is now complicating its military prowess.

Under current law, all able-bodied South Korean men are required to serve in the military for a period of 18 to 21 months, depending on the branch.
