See here how AIM-120 went from boost-sustain(pre AIM-120C5) to boost only rocket motor(AIM-120D onwards):Turns out coast and glide are the same.
There are three phases to a missile's flight. Boost lasts up to 5 seconds, then the sustainer kicks in for up to 20 seconds. The rest of the flight sees the missile coasting or gliding towards the target.
So both AIM-120 and R-37M work using this method. So does the Meteor.
Dual pulse works a bit differently. It goes, boost-glide-pulse. No sustain.
So for now, boost-sustain-glide and boost-glide-pulse are the only designs available for the current lot.
And there's Stunner, which adds an extra pulse: boost-glide-pulse-glide-pulse-glide. So triple pulse.
AIM-260 could be the first of a third type, boost-sustain-glide-pulse.
Then there are staged versions like the two-stage LREW (boost-glide-no pulse/multiple pulses, guessing), some BMDs and ASATs or AAMs with an additional jettisonable booster.
It's likely to be strategic misinformation.
Stunner's seeker is MWIR+LWIR, as is the F-35's EODAS and Python V.
So maybe it's possible that DCMAWS uses 2 sub-bands of MW rather than both MW and LW, but it's more than likely a combined system.
Dual-color is typically advertised for both MW and LW for IR.

The dual color cooled thermal module combines the advantages of both medium and long wave detection in one single 320x256@30µm detector package for high performance imaging.www.gst-ir.net
Here's a study of an NIR and MWIR dual color system.
Van der Waals two-color infrared photodetector - Light: Science & Applications
With the increasing demand for multispectral information acquisition, infrared multispectral imaging technology that is inexpensive and can be miniaturized and integrated into other devices has received extensive attention. However, the widespread usage of such photodetectors is still limited by...www.nature.com
So typically we are talking about 2 different bands rather than 2 sub-bands.
We have bought 384 ASRAAMs for the Jaguar, but our total requirement is 8000+ CCMs. It could climb up to 12000 if we are moving towards 60 squadrons, not counting IN's inventory.
While you never know, it's still difficult to assume the IAF will be buying something as a stopgap for just a few years. This type of missile is very expensive, and even more so if it's spread out across multiple bases, and you even have to train multiple personnel. That's why stopgaps for weapons are normally reserved for known weapons, like RVV-MD and SD.
There are enough Rafales for a Balakot type situation anyway. LCA will add to that pretty soon.

R-37M, as the official brochure which I posted, has dual-thrust or boost-sustain motor. It's quite different from the current AIM-120D's motor.
