This act shall be deemed to be supplemental to the existing laws governing and affecting the militia and national guard of the state, and all provisions of law relating to the government, maintenance, equipment and discipline thereof shall apply equally to and govern the naval forces as a portion thereof, unless such provisions of law be inconsistent with the different nature of the service or contrary to the express provisions of this act. In construing such provisions of law, words or language strictly applicable to the land or military forces alone, by reason of their meaning, and having an equivalent in naval parlance, shall be construed and interpreted as meaning and intending such equivalent words or language. Whenever the laws of the state governing or affecting the militia or national guard, the laws of the United States relating to the government or discipline of the army of the United States, or the articles of war, or regulations governing the army, are referred to and made applicable to the national guard, the same shall be construed to mean, when applied to the naval forces, the laws of the United States relating to the government or discipline of the navy of the United States, or the articles of war of the navy, or the rules and regulations governing the navy, as the case may be.
