They are mercenaries from all ranks possible, im more surprised that a bunch didnt go rouge or run. Mercs on this world are kinda respectable i guess.
On other note, using termals (aka IR) on space seems not optimal too, i mean, some debrits probably are also hot af and they are in space so it will take some time for it to lose heat.
Probably would be best a combination of sensors ( IR, moviment and proximity sensors, light sensors, etc). and enven if you need better processing speed i think there are better ways than IR.
