Some common virtual units:

AA: Anti-aircraft Gun. Considered a virtual unit for rule sets where it can not be taken as casualty
BBomb: Offshore bombardment from Battleship, supporting amphibious assults.
BBx: The first hit of a battleship for rulesets with two-hit capabilities. Modelled as a virtual unit with 0 in attack and defense.
SUBM: Flags that all attacking submarines should submerge when possible, after all units preceeding this virtual unit are lost.
RET: Flags that attacker should retreat at first opportunity when all units preceeding this virtual unit are lost.
