Someone must have been reading what posters here have been discussing, the Russian's are deploying their 1RL239 artillery locating radar and their "Big Fred" 1RL232 battlefield surveilence radar. Just goes to show you never know who's reading your posts.
Aren't both vehicles capable of being used as counter-battery radars? In which case why have or even use both? Maybe one is just more specialised or has a longer tracking range than the other? A book covering specialised vehicles such as this (especially Soviet AFV's) would be a real interesting read for sure.
This is a surprise?
I am beyond confident that this form, and many others, are gleamed for freebies. Look at the collection of SME's (subject matter experts) you have, sitting under one cyber-roof.
As for Ivan bringing more toys to the party...(popcorn munching).
