Go to Normandy and use this well known paratrooper rifle the M42 rifle that can be used even by riflemen or the M1943A1 automatic rifle for assaulters. You and your team may even have stuff like the M1942G42 and the M1934PT machine guns and other kinds of wonder engineering mankind ever invented.
As for certain tasks, the M5PA and the M6TE medium and heavy tanks both of them having cute cat nicknames would do the job along with planes like the P-188 bomber with 500lb bombs or the P-410 with the rockets.
Plus your team will mostly be high ranking officers of the army with some marshals helping you do the tasks given to you by the event to celebrate with the defeat of your enemies. To Victory! For the silver orders, boosters and the hero reward!
