Should i just focus on cardio for now?

focus on cardio, but dont forget that the muscles is the body mechanics that burn the CALS... so you must eat correctly to feed the muscles

I have similar goals and have given the strength training away until I hit my target weight. I'm focusing on getting fitter. Can always do weights later.

I would say both to be honest!!! Mix it up!!!

Diet is key though - All about calories in v's calories out!!

Abs are made in the kitchen : )

Im for both. Muscle takes time to build uop so it makes sense to protect and limit loss from the muscles you already have so when the fat finally goes you have soemthing to work with rather than starting way back. More muscle can give you more endurance as well which helps you exercise more effectively.

My husband is a Marine. My best advice, you need to work both cardio and strength training. Get with your recruiter and go over what you need to do at a minimum to pass both the PFT and CFT. You need to run to get to your 18 min 3 mile, 3 pull ups, and what is it 100 situps I believe, for the PFT. For the CFT you need to be able to complete the ammo can carry, firemans carry, grenade throw and a sprint ( there might be more to the CFT, but it's early in the morning and I can't remember for sure). If you can meet the minimum for those, you should be able to drop those pounds. Get serious, during boot camp and schools, you are going to be PTing pretty much every day. And I can tell you, if you get someone like my husband as an instructor, he's going to be running you into the ground.
For what it's worth, at our last company family day, they had the kids doing ammo can carry and firemans carry. Our daughter is 6 and made it nearly 30 feet on her own with the ammo can, that weighed only 8 pounds less than she does.

An 18 min 3 mile and 100 sit-ups is what, max?

Work both... Doing cardio is great, but a minimum strength test pass is required to get into BCT. Check with your recruiter to find out what you need for qualification to get into BCT when you get there vs worrying about the PFT. PFT will work itself out once you get there, if you're committed.

That might be max, my husband always pushes his Marines to get perfect scores. But if he works towards those goals, while watching his diet he should be able to make it. And if he is already in good shape going in to boot camp, that 13 weeks will be easy.
