One of the scary things to me about this is that if something that can be made to look like this robot becomes available in a cheap enough model (same applies for drones) you can seek to overwhelm an enemy by swarming them with mostly harmless even cheaper versions (think toy robots and drones) and force the enemy to 3aste resources taking all of them out knowing that some of them might be armed, but not which.

E.g. you can buy $4k or so quadruped robots on Aliexpress while Boston Dynamics' ones reportedly costs in the $200k range. If you get that kind of ratio, for twice cost you can "augment" your armed robot with 50x decoys to drive up your opponents cost to eliminate the threat 50-fold..

In other words, I expect when these end up getting used, sooner or later it will be swarms of them...
