158th Infantry Regiment ( United States ) The 158th Infantry Regiment ( " Bushmasters " ) is an infantry unit of the Arizona National Guard . The regiment has served in World War I , World War II and Afghanistan . In 1967 then Governor of Arizona Jack Williams signed into law that December 3 would be " Bushmaster Day " in the State of Arizona in honor of the regiment ' s service . History . The 158th Infantry takes its lineage directly from the Confederate Arizona Scout Companies raised by Arizona Territory Governor , John Robert Baylor The Arizonians engaged in hit and run tactics against the invading Union forces of the California Column , their most successful encounter being the Battle of Picacho Pass . However Confederate forces were soon forced to abandon Arizona and retreat into Texas . The Arizona Scout Companies formed under the command of Lt . Col . Philemon T . Herbert and would continue to fight through the war until Southern defeat in 1865 . Returning Civil War veterans and citizens formed on 2 September 1865 the 1st Arizona Volunteer Infantry part of Arizona Army National Guard . It participated in a number of campaigns against the Apache during the Apache Wars and comprised companies of Maricopa and Pima American Indians . During the Spanish – American War the unit adopted as the motto " Cuidado " a Spanish word meaning " take care " in reference to when they would patrol for them to be on guard . However , later the term would be applied far more liberally when the 158th was conducting jungle warfare training in Panama and the deadly pit viper from which they drew their nickname infested the jungle , from here Bushmasters would tell each other to beware of the snake . In 1916 , during the Pancho Villa Expedition , an expeditionary force led by General John Pershing into Mexico , the 1st Arizona Volunteer Infantry guarded and patrolled the border between Douglas and Naco , Arizona until World War I was declared on 6 April 1917 . World War I . The 1st Arizona Volunteer Infantry was drafted into federal service 5 August 1917 , re - designated as the 158th Infantry Regiment ( 1st Arizona Infantry ) as part of the 79th Brigade , of the 40th Division and was sent overseas to France in August 1918 . The regiment saw no active service at the front , however its men furnished replacement personnel to other units and was honored by acting as guard of honor to President Woodrow Wilson during his visit in France in 1918 with the 158th Infantry Band chosen as Wilson ’ s honor band . The regiment was inactivated as a federal unit on 3 May 1919 . Inter - War period . In 1924 , F Company was formed as an all - Native American unit made up of alumni of the Phoenix Indian School . World War II . After the national army reorganization after World War I , the regiment was assigned to the 45th Infantry Division . At the outbreak of World War II , the unit was activated into Federal service on 16 September 1940 and started training at Fort Sill , Oklahoma . The regiment then moved to Camp Barkeley , Texas in February 1941 and conducted maneuvers in Louisiana . After the United States declared war on 8 December 1941 , the unit was detached from the 45th Division and was sent to Panama for jungle training and protection of the Panama Canal Zone arriving 2 January 1942 . This was done as the " square " divisions of the Army National Guard were being transitioned to the triangular division TO & E in 1942 , they each " shed " an infantry regiment , leaving several trained and operational " orphan " regiments available for independent service . Unlike other Regiments which were relinked to form new divisions the 158th was left alone , either because of its location or the diversity within its ranks of ethnic groups that weren ' t desired by most line commanders . The regiment adopted the name " Bushmasters " after the venomous pitvipers found in South America , replacing the name " 1st Arizona Infantry " . Each combat soldier in the regiment received extensive training in jungle warfare , knife fight ing , and unarmed hand - to - hand combat techniques . With the formation of the 6th Army , led by General Walter Krueger , and allocation of the 158th Regiment to the 6th Army , the " Bushmasters " were sent to Brisbane , Australia arriving on 16 January 1943 . When the 6th Army ' s headquarters moved to Goodenough Island , New Guinea the 2nd Battalion , 158th Regiment provided security to the headquarters . The 158th Regiment less 2nd Battalion landed on the unoccupied island of Kiriwina , New Guinea as part of Operation Chronicle , on 30 June , for the purposes of occupying the island for the construction of an advanced base and airfield . The regiment was spread out between Kiriwina , Woodlark and Goodenough Islands in New Guinea Company G , 158th Regiment embarked for Arawe , New Britain on 15 December , as part of Operation Director and was soon joined by the remainder of the 2nd Battalion and began combat duties in the Arawe area .

At Finshaffen , the 158th Regiment was redesignated the 158th Regimental Combat Team . A 1943 article in Popular Mechanics recorded the abilities of the individual " Bushmaster " jungle soldier : " One of America ' s most colorful and least known soldiers of World War II is the Bushmaster . . . His tactics are borrowed from native jungle fighters , the American Indian , British commandos , exponents of judo and the Shanghai underworld . . . ( He uses ) machete s , curved knives , tommy guns , high - powered rifles , and hand grenades . . . His average age is 22 and his favorite weapon is the long - bladed machete . . . With his fellow Bushmasters , he disappears from civilization for weeks at a time . The men know how to sustain themselves on wild fare supplemented by ( jungle ration s ) carried in their packs . When they are not testing their camouflage against aerial observers , making camp in a swamp , or working out an intricate code of communications , they are practicing jujitsu or improve on the native ' s technique with the machete . The Bushmaster bows to no man in the art of hand - to - hand fighting and any unwary ( enemy ) who crosses his path would probably never know what hit him .

Then on 1 April , the regimental combat team invaded the Bicol Peninsula , landing at Legaspi . F Company was made up most of Native Americans from the main tribes of the Salt River Valley , but was led by white officers . Many of these officers , who survived combat , later recounted participating in Native American rituals ; such as becoming blood brothers and purifying their warrior ' s sprit before battle . Although these rituals are not today performed by the majority of the units soldiers , they still use Japanese saki to toast with in reference to the supply captured by the regiment during its time in the Philippines .
