Movement makes the Reich grow strong, 

Each piece flowing right along. 

From the front to processing, 

Every part must smoothly sing.

The reports from the morning's advance sat half-reviewed on Tanya's desk. Her cheerful humming paused only briefly as she noted an interesting pattern in the casualty figures.

"These failure rates are wonderfully consistent," she told her staff, genuinely pleased. "Three companies breaking under pressure, two artillery batteries missing targets, and a logistics squad losing half their supplies." Her smile brightened. "Enough to justify activating the new processing facility!"

She signed the orders with practiced efficiency. Units that failed would flow backward as fresh ones moved forward. A perfect circulation of resources.

"Sir," Major Serebryakov interjected, "Shouldn't we process them here at the front?"

Tanya's laughter echoed through the command bunker. "And waste all that potential? No, no - field processing is for emergencies only. Proper evaluation requires proper facilities."

Like a river flowing clean, 

Moving parts must shift unseen. 

From the front where some must fall, 

To the rear where use calls all.

The afternoon brought the first transport trains. Tanya supervised the loading personally, her melody never faltering as failed units were efficiently cataloged and loaded.

"See how beautiful it is?" she asked her staff as they watched another train depart. "Every failure at the front becomes an opportunity in the rear. Mining always needs bodies. Plague quarantine zones need medical staff. Even combat failures have value when properly reallocated."

She noted with satisfaction how the sight of loading trains improved nearby unit performance. Nothing motivated success like watching failure's consequences roll away.

Forward march the strong and true, 

Backward flow the waste into, 

Processing that serves our need, 

Making worth from worthless deed.

A messenger arrived with news from the rear facilities - they were ready to receive the day's intake. Tanya's eyes lit up as she reviewed their capacity figures.

"Wonderful! We can clear the holding areas." She turned to her staff. "Have the failed units stripped of unnecessary equipment before loading. No sense shipping uniforms and gear they won't need in their new roles."

She personally inspected the collection point. Uniforms, weapons, and equipment were efficiently sorted while their former owners waited in simplified garments for transport.

"The Reich advances through perfect circulation," she explained happily. "The worthy move forward, the unworthy flow back, and everything of value finds its proper place."

Watch them flow like tide at sea, 

Each part moving endlessly. 

Front to back and back to use, 

Till the Reich has what it choose.

Evening found Tanya reviewing the day's transportation manifests while directing the front line advance. The dual rhythm of victory and processing created a perfect harmony.

"Tomorrow we'll inspect Processing Facility Three," she told her staff, her tune shifting to match her anticipation. "Today's failures should be arriving for evaluation by then."

She added a final note to the day's report:

"Advance continues. Resource flow optimized. Failed units redirected. Processing facilities at full capacity."

The Reich's great machine moved in two directions - ever forward at the front, and steadily backward to the processing centers. And Tanya's song carried on the wind in both directions, a melody of perfect efficiency.
