Military Altars
In descriptions of Roman sacrificial rites, five different terms for designating the altars are commonly used : focus, foculus, mensa, ara and altaria. Of these, the last two appear most frequently, and ara appears to be a more ancient term. They are the common designations for any place of offering, without regard to the use of fire in the ritual.

"Soldiers were required to participate in a number of official Roman religious rites held by their regiment at regular times in the year. These included religious parades in honour of the most important Roman gods, especially Jupiter, the supreme god of the Roman pantheon: many altars are headed with the letters IOM (Iovi Optimo Maximo: "to Jupiter the Best and Greatest"); Mars, the god of war; and Minerva, as that goddess is also associated with war. These parades were accompanied by animal sacrifices and feasting. Another important regimental cult was emperor-worship. Parades were held on imperial birthdays, when the imagines of the ruling emperor and of deified previous emperors would be saluted and offered sacrifices by the prefect of the regiment."
"Soldiers were only permitted to honour such non-Roman gods as had been officially approved by the collegium pontificum ("Board of High Priests") in Rome, which regulated the state religion. The board would assess whether a foreign cult was acceptable. If, a non-Roman god was officially annexed to a Roman god on the basis of shared characteristics[ e.g. Mars Toutates, the assimilation of a Gallic deity to the Roman god of war. In practice, off-duty soldiers were allowed to follow whatever cults they pleased, providing they were not specifically prohibited."
