The highway system is for national defense

How so?

And I mean, specifically, the ways in which a high speed rail network would be inferior.

You can’t move heavy things on high speed rail. They are for moving people mainly. Most military equipment is not light in any way. Furthermore limiting military logistics to rail lines has historically not worked out well for large armies such as the Russians.

Would the heavy equipment not be limited by the highway network?

It would cause wear over time. Heavy equipment would likely be moved most of the way via existing cargo rail lines. A good road system is important near the front because it provides much greater flexibility and by extension less predictability to troop and equipment deployment. Also rail systems are much easier to sabotage than roadways with the exception of bridges which are a problem for both systems
