War in Ukraine stalls two years after Russian invasion. Russia takes the initiative with timid advances due to the shortage of ammunition for kyiv's troops.

Analysts predict a long conflict in which neither side is making progress. “The most effective way for Ukraine to regain its advantage is to build an effective defense that reduces its needs,” says Franz-Stefan Gady of the International Institute for Strategic Studies (IISS) This expert estimates that kyv will need between 75,000 and 90,000 artillery shells each month to achieve that goal.
