The Marine Corps Military Occupational Specialty (MOS) 3531 refers to Light Armored Vehicle (LAV) operators. While specific numbers of MOS 3531 marines deployed to Vietnam are not readily available, it is known that many marines in various roles operated vehicles during the Vietnam War. The use of armored vehicles was critical in the conflict, but the exact count of those specifically classified as 3531 is not well-documented. The overall Marine Corps presence in Vietnam included over 500,000 personnel at the peak of the war.

Can mp's wear a combat infantry badge serving in combat in Vietnam?

No. Unless he was later assigned to an INFANTRY unit and that unit (his unit) was directly involved with combat operations with a hostile enemy. "Only" during the Vietnam War could a GI with an artillery, armor, MP, engineer, etc. MOS obtain a CIB if he was assigned to a 11B (MOS) job in the US Infantry and engaged in combat with the enemy. A artilleryman, armor crewman (tank crewman), MP, etc. could be transfered to a grunt unit and end up in contact w/the enemy; WITHOUT his primary MOS being changed. Thus qualifying him to wear the CIB. The 11B (nicknamed 11Bullet Stopper in Vietnam) would or could be awarded as his secondary MOS. Regardless of the MOS change or not, if he was in a grunt outfit and he was in "enemy contact" with that outfit, he's awarded the CIB (on orders). After Vietnam the US Army took the MOS far more seriously and awarded it to only 11B men. But during the war men were needed everywhere all the time! Consequently the needs of the service came first and awards came after those needs were served. Another words after Vietnam "it took an act of congress" to pull a tanker off his machine and put him in another MOS, especially if he didn't like it. But during the war a man went where he was ordered...like it or not.

The Military Occupational Specialty (MOS) for a USMC door gunner during the Vietnam War was 0331, which designated them as a machine gunner. Door gunners were primarily assigned to helicopters, such as the CH-46 Sea Knight and UH-1 Huey, where they operated machine guns to provide suppressive fire during troop insertions and extractions.
