Russian doctrine of advancement on tactical level engagements seems like madness, but there is an effective method behind it.
First they send small groups of decently equipped fighters to seize a new patch of land. If/when these succeed, they instantly send in the diggers. These may not even have weapons, their only purpose is to dig foxholes and entrechments while the first wave holds the ground. Once the diggers have the first holes ready, they send second rate troops to hold the new positions and relieve the first wave to prepare for the next attack
And since they do not seem to care about casualties, this method works like a very slow meat grinder. Simply and effectively.
