Targeting your own units definitely is possible. You just have to drag-click: select the attacking unit, press and hold the LMB next to the target, drag the cursor on top of the target, release. This circumvents the selection of the target; that happens on the mouse button press, not release.
Killing silos should also be possible, that's in the basic game code for ages. If it wouldn't work, you'd get sync errors quite frequently. it just requires much more micromanagement and attention than I ever was able to dedicate, so I can't *confirm* it works.
