Countably Paracompact Space is Countably Metacompact

Theorem
Let $T = \struct {S, \tau}$ be a countably paracompact space.

Then $T$ is countably metacompact.

Proof
From the definition, $T$ is countably paracompact every countable open cover of $X$ has an open refinement which is locally finite.

Consider some countable open cover $\mathcal U$ of $X$.

Let $x \in X$.

Then there exists some neighborhood $\N_x$ of $x$ which intersects only finitely many elements of $\mathcal U$.

Thus $x$ itself can be in only finitely many elements of $\mathcal U$.

Hence $T$ must be, by definition, countably metacompact.
