A short range missile (such as GMLRS, which HIMARS also fires) does not have the glide kit. This means the missile is much faster, but for maximum range the missile has to follow a (vaguely) ballistic trajectory. With the glide kit, it can trade much of that speed into additional range by gliding to the target. This means GLSDB gliders can hit targets at further range, but being slower, it's easier to shoot down and makes it less able to hit extremely time sensitive targets. IIRC, GMLRS missiles have a time-to-target of 2-3 min from launch, while GLSDB gliders have (a guesstimate on my part) more like 10-15min from launch. GLSDB gliders can also sacrifice some of the range to loop around and hit targets from different angles, while GMLRS missiles are pretty much only top-down. GLSDB gliders are also significantly cheaper than GMLRS missiles.
Appreciate the informative response!
I'm ashamed to say it hadn't ever occurred to me that a missile still needs to follow a ballistic path.
I've been fooled by movies without realising the nonsense in that, given they have no 'wings'. Control surfaces aside of course. Thanks!
For additional reference, we now have video of a GLSDB in action in Ukraine.
Holy shit yeah that's a step up from drone grenades footage, nice!

GLSDB gliders go 93 miles.
GMLRS missiles go 57 miles.
