The voice in this recording sounds like the same officer throughout. A rough translation is given below:
A command of some type then:
"Brothers! I drink to the health of our majestic leader Emperor Nicholas Alexandrovich...Hurrah!"
The anthem "God Save the Tsar" is played along with cheers...then
"On with the ceremonial march! Regiment! Go!"
The march "Varshavianka" is played...then
"Brothers! Thank you for the great parade"
Troops answer: "Glad to try, Your Excellency"
More music...then
"Thank you, brothers, for great maneuvers"
Troops answer in the same manner, like in the first time. But their cry does not seem to be "Imperial Majesty" as would be expected if this were the Emperor.
Perhaps I am wrong but the voice always seems to be the same general.
