English lyrics (probably a pretty rough translation):

Himno De La ACIM N° 51 (Hymn of the ACIM N° 51)

Lyrics: Hermann Brokordt Ramírez
Music: Héctor Arredondo Soza

I am a commando, a marine,
for I will engrave my courage with fire.
That's why I go on snow,
waves, sky, sun and salt.
With my dagger,
I fight until winning.

That's why I go on snow,
waves, sky, sun and salt.
With my dagger,
I fight until winning.

Quick step alongside fierce comrades
who do not miss when firing.
And from the sea, by
air or land will I infiltrate,
and without fear,
my life will I then give.

And from the sea, by
air or land will I infiltrate,
and without fear,
my life will I then give.

When I return with combat wounds,
I will not hesitate in singing with strength:
"I am a commando, a strong and faithful marine,
for I have already engraved my courage with fire.
I am a commando, a strong and faithful marine,
for I have already engraved my courage with fire"
