That works or you could start the comic off at the GG's base near the resort and showing the day to day lives of the GG's as well as GG's getting to *know* one another as well as slowly introducing the main GG's characters then have a few GG's heading to the resort for some R&R and then have the SRC attack the resort while the GG's that are at the resort are doing their best to save the civies while calling for reinforcements from the GG base and have the SRC killing people left at right as well as a few GG cannon fodder before the GG reinforcements show up for a grand battle.
