The most precarious of these quake-lakes was the one located in the extremely difficult terrain at Mount Tangjia in Beichuan County, Sichuan, accessible only by foot or air; an Mi-26T heavy lift helicopter belonging to the China Flying Dragon Special Aviation Company was used to bring heavy earthmoving tractors to the affected location. This operation was coupled with the work done by PLAAF Mi-17 helicopters bringing in PLA engineering corps, explosive specialists and other personnel to join 1,200 soldiers who arrived on site by foot. Five tons of fuel to operate the machinery was airlifted to the site, where a sluice was constructed to allow the safe discharge of the bottlenecked water. Downstream, more than 200,000 people were evacuated from Mianyang by June 1 in anticipation of the dam bursting.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many soldiers had to travel to the area by foot?
Ah, so.. 1,200

Municipalities (Gemeinden): Every rural district and every Amt is subdivided into municipalities, while every urban district is a municipality in its own right. There are (as of 6 March 2009[update]) 12,141 municipalities, which are the smallest administrative units in Germany. Cities and towns are municipalities as well, also having city rights or town rights (Stadtrechte). Nowadays, this is mostly just the right to be called a city or town. However, in former times there were many other privileges, including the right to impose local taxes or to allow industry only within city limits.

Ah, so.. municipality
