I did not have any assembly sheet either.
Then again the assembly is not too complex. only some figures have more than 3 parts (the exo suits mostly). the drones are quite trivial and most of the figures just have arms or weapons to glue (the raid44 ones also have heads to glue).
It's trickier to clean the glueing surfaces and make the pieces stick because some are very flimsy and have a very small glueing surface to hold a bit of weight (specially the swords with the "sisters" model)...
I have expensive snips and a selection of hobby files , this all helps.
