There's only one objective in this map: seize the town of Mersa el Brega. The maps starts with both Italian and German troops dropping in, where most of the Germans already have been given Start Commands. You have the option to let them wreak some havoc or take over their command. The latter option is probably the best as they will run into an entrenched enemy/AI, right beyond the dried river.

If you go attacking frontal, prepare for a bitter fight. An easier way, however, would be by going over the coast and attack their flank.
