Back when I was stationed in Hawaii, 3/4 Cav was the divisional cavalry squadron. Today, it’s the cavalry squadron assigned to the 3rd BCT of the 25th ID.
I never dealt with the TOW mounted on Humvees, nor with the ITAS. All my TOW experience was with the Bradley.
Though I seem to recall that Esli and I climbed around on an M901 at Paine Field at an air show once.
