Little/ no military training (conscripted dark masses)
Lack weapons/ ammunition
1/3 Russian soldiers had no rifle (6.5 mil men but 4.6 mil rifles)
Had to get rifle from dead soldiers
Used all ammo in 6 months
Sukhomlinov (War Minister) old fashioned: use horse and sword, storm trench with bayonets, hand combat… LOL
Poor leadership (chosen loyalty Tsar, bloodline)
Not enough food, supplies, clothing, bedding
Soldiers demoralised, wanted become POW (bad to fight, bad at home): POW to dead ratio 16:1
5 mil casualties (battle, disease, starvation)
