ACtually, a good amount of the data supplemented in the OP is false. It has a scope, it does NOT shoot/see through walls, and it indeed does not fire up. You point it at a target, fire, then you have to put the system down for the rocket to be controlled by it.
While we're in the topic of RLs, an AT-4 (It shoots an 84mm rocket

) Would be nice. It's a disposable RL that fires once, and is then just dead weight.
