It's not body armor and such that matters. It's control. Wizards have mind magic. They can alter memories and control people. That would let them act through agents who already possess muggle resources, and who already understand (and can explain whenever necessary) the strengths of the muggle world.
At the end of the day, if wizards seriously get interested in the muggle world, and muggles in the wizard world (not that they should get the chance, if the Malfoys are smart), and both learn about each others' strengths, wizards will still be the ones with the edge.

This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 97. The previous thread is at nearly 500 comments.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system.
Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25.
