====Cabin Sealing====
To compensate for the lack of air tank by default, mechs with enclosed cabin (e.g. all except Ripley) got an ability to toggle cabin exposure to the outside air. Exiting the mech makes cabin air automatically exposed.

When you seal the cabin, it traps some of the outside air inside the cabin and you can breathe with this air to perform a short space trips. But the oxygen will run out quickly and CO2 will build up.

Sealing the cabin in space will make the cabin filled with vacuum, and it will stay there until you return to air environment and unseal the cabin, letting the breathable air to enter. There are temperature and pressure sensors that turn yellow/red when the corresponding warning thresholds are reached.

You could also use personal internals in combination with cabin sealing for long space travels, so Air Tank is completely optional now and mostly needed when you need RCS thruster.
