“Russian leaders will post junk weapons...”
Umm, no. The Iskander-M is a mobile, multi-role strike weapon.
“The Russian Iskander-M cruises at hypersonic speed of 21002600 m/s (Mach 67) at a height of 50 km. The Iskander-M weighs 4615 kg, carries a warhead of 710800 kg, has a range of 400480 km, and achieves a CEP (Circular error probable) of 57 meters. During flight it can maneuver at different altitudes and trajectories and can turn at up to 20 to 30 G to evade anti-ballistic missiles. For example, in one of the trajectory modes it can dive at the target at 90 degrees at the rate of 700800 m/s performing anti-ABM maneuvers.[4][9]
“The system is intended to use conventional warheads for the engagement of point and area targets, including:
hostile fire weapons (missile systems, multiple launch rocket systems, long-range artillery pieces)
air and missile defense weapons, especially stationary
fixed- and rotary-wing aircraft at airfields
command posts and communications nodes
troops in concentration areas
critical civilian infrastructure facilities
That’s also a Russian army weapon for use against ground targets. It’s no match for what NATO armies can do.
On speed, a Scud will go mach 5, but it can be stopped.
