If they can't swim more than 200 yards they aren't very good swimmers. When I was a kid and swam competitively the senior team (13-18) swam 3.5 - 5 k per workout (1.5 - 2 hours). We had a timed 3k swim and a timed 5k swim every year as well. Of course this was all pool work.
As for advice, that depends on what you want. For endurance you just have to swim, a lot. Learn to strike a pace and maintain it, accelerating is really tiring. For open water practice head up strokes - side stroke and head up breast stroke. If you need to get somewhere in a hurry then a head up crawl, or a combo of head up/head down crawl. For an example of a head up crawl think water polo.
For "tactical" type situations practice in full clothing - boots/shoes, socks, pants, shirt, jacket - the lot. Start in shallow water because the drag of all this crap is alarming. Practice taking footwear off, particularly heavy boots. Don't take it off if you don't need to though.
For survival type stuff, that depends on water temperature. If you're in cold water, you'll get hypothermic extremely quickly so heat and energy conservation are key. Hopefully you've got something warm on, keep it on. Keep your head out of the water - water sucks heat away much faster than air. If you've got a lifejacket or PFD on you've got a much better chance of survival, learn the "survival pose" - curl up in a ball and keep your armpits and groin covered. The major heat loss areas are head, armpits, groin. If you don't have a PFD or lifejacket, you can also remove your pants, tie knots in the legs, and fill them with air by striking the water with them - this may give you some flotation but you lose a lot of heat this way.
It's not the SEALs but it's a start.
