Maybe it's only a glitch with my game. This is in the 3rd mission of the Ukrainian campaign where your platoon clears out a factory complex. Once hitting aqcuire on both the atgm launcher and the missile, it shows the missile in the infantry unit's inventory, but the launcher disappears from the game, doesn't indicate it anywhere on the squad. I do notice that while it shows the ATGM missile icon in the rifle squads inventory, it doesnt show up in the white inventory list.
