Not sure how much semantic difference there is:
The arms industry interlinks with both the executive branch and the uniformed military—there’s a lot of evidence that MIC pressures were significant regarding the shift to a more hardline foreign policy in the late 1970s, so the MIC can be a significant factor in policy formation.
I'm also not sure about (1) vs. (2)...the latter maybe sounds better but not sure why:
(1) The arms industry interlinks with both the executive branch and the uniformed military
(2) The arms industry interlinks both with the executive branch and with the uniformed military
