[x] Find a river or something to wash the blood off in and get a change of clothes from one of your scrolls. Sure, it hurt in the moment, but your body is able to deal with it, so you should just get on with your mission.
[X] Go to one of the smaller villages serving as bases for the Ame-nin combating Iwa's scouts as well as the forces massing to blunt Konoha's potential invasion and find a medic, just in case. It couldn't hurt.
[x] The first order of business is disrupting Konoha's supply lines before they can reinforce against Iwa's more elite western forces. In theory, similar to this mission, though likely with more genin and chunin involved on the enemy side, and loose teams of jounin and chunin on your side.
[X] The first order of business is eliminating Konoha's forces before they're able to attack into the Land of Storms from the Land of Meadows and establish the foothold, turning your country into a battlefield between two great powers just like the last war.
