Modern jet powered attack drones like Cloud Shadow is huge compared to Su-25 and carry much heavier payload including stand off missiles. If Russia used drones in Idlib then wouldn't lost Su-24 and Su-25 pilots to ground fire. Modern drones can be directly controlled from hundreds of km away where pilots are safe in mobile control trucks. Also drones are much cheaper to service and build. Almost all planes used in Libya war for instance are attack drones. Manned jets days are numbered. Russia is no longer developing anymore manned combat planes. All combat planes under development are drones.
Do you even read what you post?
The Cloud Shadow is huge and is a HALE... a High Altitude Long Endurance armed drone that could never off CLOSE Air Support... based on the link you provided this drone weighs less than the weapon payload of the Su-25... the entire drone is 3.2 tons with an amazing weapon capacity of 400kgs... that is pathetic.
Sure if Russia had used drones they wouldn't have lost any pilots... but they also would not have hit any targets either and would have spent rather more money for that pathetic return. Drone pilots are not safe... the terrorists could easily determine where they are and attack them with IEDs.
Drones like this Chinese drones are much more expensive than a cheap simple fighter aircraft. The war in Libya is a civil war and meaningless for the Russians who face HATO and the US. Russia is currently introducing Su-57s... a manned aircraft... they are also introducing lots of transport types, a bomber type and also they are working on a replacement for the Su-25 in the CAS role and a high speed replacement for the MiG-31 interceptor.
MRAP is just a very bad design - The height and steepness of the dropdown stairs, not sufficiently effective against Explosively Formed Penetrators (EFP) etc.
Russia should develop an MRAP with T-72 type protection but not follow the bad design of the MRAP.
MRAPs have their purpose, but that purpose is patrol in environments where the main threat is land mines and IEDs and small arms rather than RPGs and ATGMs.
Russia is in the process of transitioning into a new group of families of vehicles... heavy vehicles, medium vehicles, and light vehicles. Their Typhoon family of vehicles would benefit from development of MRAP platforms in terms of mine resistance and light weight armour options, but would not be MRAPs as such.
Russian paramilitary forces would benefit from MRAPs but the Army not so much as they really do not replace BTRs or BMPs.
The Su-34 has the same or even better armor then the Su-25. That´s why it can be used for CAS. But it is much more expensive then the Su-25, so the best choice for such missions are upgraded Su-25´s.
The Su-34 is a medium to deep strike aircraft and is designed for low level very high speed penetration to attack specific targets, which is completely different from the Su-25 that flys low and slow and loiters around the front line attacking targets causing ground forces problems.
The Su-34 is Iskander that flys low and fast, Su-25 is a 152mm artillery piece attacking targets that hold up the advance or cause problems for ground forces moving forward.
MRAP´s were developed as cheap substitutions for APC´s and AIFV´s. A truck with some armor, nothing more. And it has to be so high to be safe from mines.
Sort of... MRAPs were developed to better protect troops who would otherwise be operating in unarmoured vehicles like humvees. Before they were used in combat most Humvee crews assumed because of their size and weight that the Humvee was armoured and had bullet proof glass. It is not and does not so while they were driving them like they were bullet proof they were not. Step one was to put armour on them which make a heavy big vehicle even heavier and unusable, so they looked to alternatives and MRAPs were the solution short of using APCs which had better protection from small arms but were not necessarily better protected from land mines and IEDS which would immobilise them and kill the contents.
MRAPs are also generally wheeled vehicles so have better mobility on roads and lower operating costs than tracked vehicles like BTRs and BMPs.
