GAMES:Red Alert
From DOSBoxWiki
Red Alert runs just fine in DOSBox.
You can download the ISOs for the game from EA (who bought out Westwood in 2002 or 2003). See the news article for more information.
You should mount both ISOs at one time, and then switch with CTRL-F4 when the game asks you. For example, I've got these two commands in my AUTOEXEC:
MOUNT c ~/emulators/dos IMGMOUNT d ~/emulators/CD1_ALLIED_DISC.ISO ~/emulators/CD2_SOVIET_DISC.ISO -t iso -fs iso
