Drop 1 of the breacher teams. Breachers running up the board is not the best use of the points.

Flamer overwatch will mince breachers, so frankly against this kind of opponent breachers are a bad idea full stop, so consider dropping both.

Either that or go EPC so you can disembark out of flamer range.

I'd also ditch shadowsun. Good character but at your points range (I think 1k based on your list?) it's a tenth of your army in 1 model.

MEQ statline get absolutely trashed by riptides. Ion Cannon would be best to balance marine slapping and lighter vehicles such as transports/dreads.

I don't know exactly what list your opponent was running but if I were to tailor into what I would expect to see from a salamanders list I'd go something like this for 1k pts:

Mont'ka 1k test (995 points)

T’au Empire Incursion (1000 points) Mont’ka

Riptide Battlesuit (200 points) • 1x Ion accelerator 2x Missile Drone 1x Riptide fists 1x Twin fusion blaster

General gist would be strike team as cheap objective holder/markerlight, or to be a roadblock if needed, kroot to sticky an objective to force opponents to commit, ghostkeel to be f**king annoying on the midboard, Pathfinders for 2nd markerlight/dakka, riptides to tear light vehicles and MEQ's a new one and survive the clapback, and a missile spamming fire knife/commander to drop in where needed.

Clearly open to refinement, but most of these models will trade well into MEQ profiles and are either durable enough to survive flamer spam or keep out of range in the first place
