And since the US lacks any sort of dedicated missile system in its TT, here are some options which aren’t TOW’s.
GLH-H

GLH-L

LOSAT HMMWV

LOSAT HMMWV would be more of a gimmick (like the LOSAT) and therefore be an event vehicle, but the Ground Launched Hellfire (GLH) series of vehicles should realistically be TT.
I don’t count squadron vehicles, because they take far longer to acquire than any TT vehicles. The message you quoted was also in regards to the M113A1 (TOW) specifically, M901 is not that.
So recently i came across 2 anti air systems that were tested by the United States. The Liberty 1 and the Shanin. Unfortunately i have very little information on them outside the fact the US tested both, and the Liberty came about after the Shanin was tested and i know both use the Crotale missile, and that the Liberty competed agsinst the ADATS. It think it would be neat if the Shanin was added to both the US and France and if the US got the Liberty
