This edition pairs hard numbers from active conflict and budget fights with the slower-moving forces that shape future capability and doctrine. Ukraine's record September casualties and Iran's drone swarm strategy show the sharp edge of current threats, while the CRS budget breakdown reveals how Washington is reweighing its global commitments. A historical look at SEAL doctrine and a Navy power electronics thesis round out the picture with institutional depth, and UN Women's counter-terrorism strategy offers a policy angle often missing from defense briefings.
