The museum consists of two storeys of the Gen. Arturo Enrile building and the adjacent Kagitingan (Filipino, "bravery" or "valor") Park. The lower level showcases the development of the Philippine military through different eras of its history. The upper level consists of displays dedicated to the Philippine Army, Philippine Navy (including the Philippine Marine Corps) and the Philippine Air Force. The Kagitingan Park is used to display decommissioned military vehicles and weapons.[1]
Notable among the museum's collections are two letters written by Apolinario Mabini to Emilio Aguinaldo concerning Antonio Luna. One of the letters, dated February 28, 1899, stated that Luna had renounced his position as Director of War Operations due to Aguinaldo's failure to censure officers who refused to obey his orders. The other, dated March 6, 1899, disclosed that Luna had published a circular order stating that he would execute anyone who refused to obey his orders. Mabini also states in this letter that Luna had executed someone in Bocaue, Bulacan without benefit of a court-martial.[1] Aguinaldo's rayadillo uniform is also in the museum's collection.[3]
