Personally I hope they have added the guidance computer they were displaying for the Su-24M and Tu-22M3, that generates projected impact points for unguided rockets and bombs in free flight.
It means a circle appears in the HUD and the pilot just manouvers the aircraft to put the circle on the target and then releases the weapon to get a good chance of a hit.
It greatly increases the accuracy of dumb weapons against the sort of visible targets the Su-25 was designed to engage, for a small initial outlay.
Most of the time precision guided weapons are good for dangerous point targets, but for most targets you want the accuracy of a guided weapon with the cost of an unguided bomb or rocket... the computer aiming system offers that.
Of course they need some guided weapons as well... GLONASS guided bombs in the 50kg, 100kg, and 250kg weight range would be ideal for using near friendly troops to hit enemy targets without leveling the whole village.
Of course if you corner some terrorists in a mountain valley a few FAB-3000 or even FAB-9000 bombs delivered by Tu-22M3s would do the trick too.
The Ugroza guidance kits for rockets would also improve the performance of the Su-25SM as each rocket suddenly gets the accuracy of an ATGM and can be used at extended ranges with confidence of a hit.
Carrying HERMES like weapons will be useful, but a 20 shot rocket pod with 80mm guided rockets each able to take out a truck or bunker with a single shot maximises its performance, and with terminal guidance it means rockets can be fired from max range which increases the safety of the aircraft by using the weapons from standoff range.
Of course these days they could have a high flying UAV with a laser target marker just circling the targets with Su-25s lofting laser homing rockets towards the targets for max standoff range and minimal exposure to enemy fire.
Fitting an Su-25 with a targeting pod like Damocles means it could operate above enemy fire and still find and engage targets much more cheaply than a medium fighter could.
The satellite navigation and laser ranging allowing the pod to calculate the coordinates of the target means that data could be directly passed to satellite guided bombs under the Su-25s wings and released in real time... lighter weight bombs minimising the threat to nearby friendly forces.
(Note my emphasis on friendly forces nearby is because the CAS role of the Su-25 is to engage targets close to friendly forces giving them problems... it might be a bunker or tank or it could be a machine gun position amongst rocks or a sniper position identified by ground forces. Bombs of 50-250kg means you can release the weapons nearer to friendly troops than you could with standard 500kg or heavier bombs safely... the precision meaning they are still effective on target despite being lighter.)
