Why do you want to secure the airfield? You will have a second-order intent behind that tactical action. If your costs in achieving the tactical action mean that you aren't able to achieve the underlying intent then you've failed. For example if you secure the airfield but basically destroy it in the process, and the whole reason to secure it was to use it, then you've done it at 'at all costs' but it was pointless. Or for example if you want to secure it in order to reassure the local population, but terrorise them in the process, then again you've secured it 'at all costs' but the costs mean it's been a net-negative. Military thinking means always working on at least second-order thinking, not tunnel visioning on the immediate objective. 'At all costs' is classic toxic tactics.
