This may not be the best but here’s how I would do it.
Counterclaim #1:
Some would argue that women should not be allowed to serve combat positions in the United States military because they don't possess the strength requirements
for difficult tasks.
Evidence #1: (This section looks good I think)
According to the text, "The Army's
own research indicates that the vast
majority of women do not possess
the lean mass necessary to meet the
strength requirements for very heavy
and heavy physical tasks"
(Fredenberg 5).
Despite the fact that women do lack the strength requirements for very heavy physical tasks, they should still be allowed to serve combat positions in the United States military. When in groups with men, they raise the team's collective intelligence which improves combat performance in the United States military.
Note: These are just my suggestions. This isn’t final. You may make adjustments accordingly. Hope you find this somewhat helpful. Good luck.
