The Ukrainian army has lost less than 10% of the provided Western
equipment in battles with the Russian invaders, the commander of
the Estonian Defense Forces intelligence service, Colonel Margo Grosberg, has said
in an interview with Estonian news outlet ERR.
We are currently seeing only one (?) of the 9 (?) newly formed assault brigades at the front. Most of the ground work is performed by the preexisting troops with various mix of eqiupement.
Afaik RUF have no strategic reserves at that magnitude (they might build some divisions, but at the cost of front line units).
-> So UAF is thinning the RUF trench lines to drain the tactical reserves and shaping the battlefield (aka blowing ammo dumps in the rear) until the supreme command decides it’s time to strike with the main force which is currently in reserve.
