The fundamental operation for reversal of a tubal sterilization is a microsurgical anastomosis. Success of the procedure depends on the extent of tubal destruction and the length of the repaired tubal segments. If the reconstructed tube has a length of at least 4 cm with an ampullary length of 1 cm, live birth rates of 60% to 80% can be achieved. The tubal pregnancy rates vary, but average 2% to 5%.

Candidates are placed in an environment of political instability characterized by armed conflict, forcing Soldiers to analyze and solve problems to meet the challenges of this real-world training.
