The proper title should have been "progress crash"...but then people would think it was political :)
Both progress, molnyia and Soyuz all use the Soyuz launch vehicle (different upper stages IIRC in some cases), as do a variety of other missions--it's their workhorse vehicle (think delta or atlas), while proton is their titan-4 / delta-heavy equivalent, and zenit is their medium unmanned (think atlas-551/2 equivalent).
Also, it's not the same Soyuz that has been in use for 40 years, any more than atlas-5 is the same atlas as 40 years ago (although they both use Russian engines :) )
