In real live wars are not fought with time table or office
hours..That does mean for training purposes, they could have a
cut of time. If there happen to a actual situation, wars will
only end after someone looses or surrenders. We could have capture
the Flag.That way it all depends on how fast a unit can get the
flag the exercise will end."Dirty Dozen" referance.
The assualt forces will get better training if they accounter
some resistance. As most training we attack the beach, few
have been done defending the beach. As in most war movies,THE
LONGEST DAY, SAVING PTE RYAN. good example, assults on beach will
train our soldiers on what they can expect to encounter.
Spit the forces to a defence and an attack force that way both
will get better trained in a single exercise. Though this exercise
could be held weeks before the fasting month but it does service a
good training for you never know when actual situation will
happen.
