大海航行靠舵手，干革命靠毛泽东思想。林彪 一九六七年十一月二十九日

Sailing the Seas Depends on the Helmsman, Mao Zedong Thought by revolution。

千钧霹雳开新宇——炮打司令部

Thank you @imluffy, I could not read the handwriting!

The first is a quote from "林彪" Lín Biāo (1907-1971) a veteran Communist military leader and Mao Zedong's designated successor until his death, which he said on "一九六七年十一月二十九日" 29th November 1967: "大海航行靠舵手" (when) sailing the seas (one) relies on the Helmsman, "干革命靠毛泽东思想" (when) carrying out a revolution (one) relies on Mao Zedong Thought.

Mao's armband says: "Red Guard".

The second one says something like:

"(at this) critical juncture the sound of crashing thunder (will) open a new universe -- Bombard the headquarters."

Mao is writing: "Bombard the headquarters".

A chinese friend tells me that the second poster is a literary allusion to: 山海经 / "Classic of the Mountains and Seas".
