Qin Dynasty sarissas?

[Intranetusa]

I was browsing armchairgeneral forums when one of the members posted links to several videos regarding the Qin armies:

Fast forward to 5:30, and it mentions 6 meter pikes used by the Qin army. The entire video only mentions it briefly for a few seconds. The historical accuracy kinda falls apart when the video shows the soldiers charging at top speed with their long spears, completely out of formation...

The video is mediocre overall, but I wanted to know what are your thoughts on the similar pikes...were they used in similar fashion as the sarissa tactically speaking? (pining down enemy infantry while cavalry/other infantry did the flanking)

Were the Qin army formations similar to the Macedonian army (combination of pikes, cavalry, and infantry?) that necessitated the use of a sarissa formation?

The video also mentions the shorter halbreds/dagger axes and spears...and how they could have been used in conjunction with the longer pikes. So was it possible to have a sarissa formation with the shorter lengthed spearmen/halbred infantry in front, while the longer pikemen were behind them? (with the pike still long enough to reach the same length as the spears carried by the infantry in front) ?
