Complete military training and lose consciousness (4,3)
I believe the answer is:
pass out
I believe this is a double definition.
'complete military training' is the first definition.
(I've seen this before)
'lose consciousness' is the second definition.
(passing out is a kind of losing consciousness)
'and' acts as a link.
(Other definitions for pass out that I've seen before include "Faint - finish military training" , "drop" , "Graduate - faint" , "In the army, do so having proved ready" , "Swoon" .)
