O Prince of peace, we humbly ask your protection
for all our men and women in military service.
Give them unflinching courage to defend
with honor, dignity and devotion,
the rights of all who are imperiled
by injustice and evil.
Be their rock, their shield, and their stronghold
and let them draw their strength from you.
For you are God, for ever and ever.
