The Carl Gustav is a fine Swedish weapon that has been in production for better than half a century, with constant refinements and improvements. As a portable, man carried recoiless rifle, it is more weight efficient than single shot, tube launched missiles. I have no doubt that Saab and its contractors will quickly be awarded contracts to produce more and that US troops will soon get new and more advanced versions than what they are now giving up.
Its already happening. The US is switching to a new lighter version called the M3E1.
