just had the chance to give it a try. Using 1.84, turn based tactical. The attack took two waves. Only thing in planet cargo were mines (no WP or Sats). Which were 22 Sm mines, with level 1 warheads.
First wave dropped:
26 troops VS 27 militia. After combat, 22 troops left, 10 militia left, and 11 mines left.
ended combat round, brought second ship to the planet.
Second wave dropped:
6 troops =
28 troops VS 10 militia. After combat 28 troops remained, zero milita, 8 mines. Planet captured.
The first wave obviously took 10 combat turns, the second wave was completed on the 4 turn. Not sure if the damage resistance of the mines had any effect, but with the exception of the one extra lost during the first battle, the planet lost one mine per combat turn from storage.
As for the troops: Sm troop, 1 shield3, 1 ABP3 (20/15/10).
Three duplicate tests showed the exact same results.

So in turn based, you can capture mines. But not all of them. I would assume the same would apply to sats or a combo of both, but have not had the oppty to check that (yet, mwahaha).

When I tried to test it using only one wave, the 32 troops VS 27 militia did not capture the planet. remaining were 29 troops, 4 militia, and 12 mines. (one mine lost per combat turn. hmmm)
