Their ‘MO’ has been known for decades. The tactic of shoot and move is not new.
I think the Javelins are shoot and move. I think theyh are shoulder fired and they lock on their target when fired. So you don’t have to guide them in, you are free to move.
By Contrast the Stugna-P can be fired remotely from a tripod. But a team has to keep lasers on the target. So the team can avoid being in the immediate vicinity of the missile when fired. But the team is tied down due to the necessity of the laser on the target.
