If it was up to me i would choose Tow infantry above the Patriot. (not going to discus the patriot here.)
But lets be fair this has bin discussed so many times before and i didn't find a real reason why this isn't in game, okay its heavy but lets face it most ATGMs are they mostly are moved by vehicle to the front lines then moved up closer and not really used as a offensive weapon, more as a defensive weapon.
Most TOW armed vehicles have bipod with them for them to mount it off and place it concealed for defensive times. Wen in offence they are mostly mounted on the vehicles designed for this weapon system.
But lets look at the game stats and compare and then finish with a real life picture:
Spoiler : :
If you look at the stats the TOW and the I-Tow are very close and to up to the same level as the other infantry launched anti tank weapons.
And the tow can be used by allot of nations that don't use the Milan or other weapons like that.
Or do i get the same old answer that the game is based on coalition decks rather then national decks with i prefer.
So for me why not i would love Tow infantry just as much as HJ-8 infantry.
Here is a picture of infantry running with a tow launcher and ammo in a operation training for the Allied Command Europe Mobile Force operation called Avenue Express in 1989.
This picture shows the Dutch Marines Whiskey Infanterie Compagnie (WINFCIE) and the Tweede Amfibische Gevechtsgroep (2-AGGP).

I just found this other picture with the same guys but the standing hold with the Tow weapon in there hands.
More pictures about this operation you can find on this site:
