Curiously, the air force is using their first ten Pantsir-S1s to guard S-300 anti-aircraft missile bases located around Moscow. There was no explanation from the Russians as to why they felt a mobile, low level anti-aircraft system was needed to guard a larger, high altitude one. Perhaps additional protection against cruise missiles

The S-300 and S-400 are pieces of technical junk. Pathetic that they are being guarded

There was no explanation from the Russians as to why they felt a mobile, low level anti-aircraft system was needed to guard a larger, high altitude one.

Probably because of a possibility of a swarm attack by several small, individually guided weapons.

At this point they probably have only a small cadre of technicians who know how to properly maintain missiles.

Perhaps they’re worried that their pal in Tehran will repay their kindness by lobbing something nasty their way.

Not being an Intelligence annalyst by occupation it seems to me that the Russians may be planning a preemptive strike against the U.S.Otherwise I can’t see why Russia would build a multilayer defence thats Not needed.

With Obama destroying our military by the day we sure are No threat to Russia now and never have been.

The only other reason I see to beef up those missile defences is China’s growing military strength is making Russia a little uncomfortable.

From Air Power Australia:

The latest Pantsir S1 configuration at MAKS-2007, carried by an 8 x 8 KAMAZ-6560 chassis. This variant incorporates a new Phazotron designed agile beam phased array engagement radar, derived from Phazotron's earlier effort on the Zhuk MF PESA air intercept radar. The primary design aim for this system was the interception of PGMs [sic], especially the AGM-88 HARM and GBUs (via Vestnik PVO).
