I would be careful with this particular point (emphasis mine):

200-300 people died in clashes in various parts of Beijing, around June 4 — and about half of those who died were soldiers and cops..

The article does not say where the "half" figure comes from or give evidence for soldier deaths being that high. The estimate is only mentioned briefly in passing.

Some calculations have up to half the dead being PLA soldiers trapped in their armored personnel carriers, buses and tanks as the vehicles were torched.
