Exercise 2: From the 1937 Purge to 1941 - Possible Solution
==================================================================================================================

This exercise is asking you to trace a real, direct connection between
one specific event (Tukhachevsky's execution) and a consequence that
didn't materialize until four years later, rather than treating the two
as coincidentally related by timing alone.

WHAT THE TUKHACHEVSKY TRIAL ACTUALLY TRIGGERED
Tukhachevsky's execution on fabricated conspiracy charges wasn't an
isolated event - it opened a real, much broader purge running from the
top of the Red Army's officer corps down through the rank and file,
removing experienced commanders on a genuinely large scale over the
following months.

WHY REMOVING EXPERIENCED OFFICERS HAS A REAL, LASTING EFFECT
Military competence at senior levels depends heavily on real,
accumulated experience - years of training, command practice, and
institutional knowledge that can't be quickly replaced simply by
promoting the next available officer. Purging a large fraction of that
experienced leadership doesn't just create a temporary gap; it leaves
an army genuinely less capable for as long as it takes new leaders to
develop equivalent real experience.

WHY THIS SPECIFIC GAP MATTERED IN JUNE 1941
By the time Germany invaded in June 1941, the Red Army's own senior
command had not had the years typically needed to rebuild the real
experience purged out of it in 1937-38. Historians treat this as a
genuine, significant factor in the army's own well-documented early
failures against the German invasion - not the only cause, but a real
and direct one, tracing back specifically to the 1937 purge rather than
to any failure in 1941 itself.

ANSWER: The connection is real and direct because purging the officer
corps in 1937-38 removed a genuine reservoir of military experience and
competence that couldn't be quickly rebuilt, leaving the Red Army
structurally weaker at exactly the command level it most needed when
Germany invaded in 1941 - a documented consequence of the earlier
purge, not a coincidence of unrelated timing.

WHY THIS WORKS AS AN ANSWER
------------------------------
It explains the actual mechanism (loss of irreplaceable experience, not
merely loss of specific individuals) connecting a cause in 1937 to a
consequence in 1941, rather than simply asserting the two events are
related.
