abstract: 'We present measurements of secondary cosmic microwave background (CMB) anisotropies and cosmic infrared background (CIB) fluctuations using data from the South Pole Telescope (SPT) covering the complete 2540 deg$^2$ [SPT-SZ]{} survey area. Data in the three [SPT-SZ]{} frequency bands centered at 95, 150, and 220GHz, are used to produce six angular power spectra (three single-frequency auto-spectra and three cross-spectra) covering the multipole range $2000 < \ell < 11000$ (angular scales $5^\prime \gtrsim \theta \gtrsim 1^\prime$). These are the most precise measurements of the angular power spectra at $\ell > 2500$ at these frequencies. The main contributors to the power spectra at these angular scales and frequencies are the primary CMB, CIB, thermal and kinematic Sunyaev-Zel’dovich effects (tSZ and kSZ), and radio galaxies. We include a constraint on the tSZ power from a measurement of the tSZ bispectrum from 800 deg$^2$ of the [SPT-SZ]{} survey. We measure the tSZ power at 143 GHz to be $D^{\rm tSZ}_{3000} = 4.08^{+0.58}_{-0.67}\,{\ensuremath{\mu {\rm K}^2}}{}$ and the kSZ power to be $D^{\rm kSZ}_{3000} = 2.9 \pm 1.3\, {\ensuremath{\mu {\rm K}^2}}{}$. The data prefer positive kSZ power at 98.1% CL. We measure a correlation coefficient of $\xi = 0.113^{+0.057}_{-0.054}$ between sources of tSZ and
