Sometimes it was mosquito repellant; but 99% of the time it was LSA (Lubricant, Small Arms). If a GI didn't have some LSA, he sure had to borrow some from one of his buddies (and that buddy would tell him in very clear words to start packing his own LSA!). Every weapon carried by GI's in Vietnam, from the .45 pistol to the M16, to the M60 and .50 caliber machine guns were semi or fully automatic weapons...and they NEEDED constant lubrication. If they didn't get lubed...they JAMMED! Machine gun belts of 7.62mm (.308 cal) and .50 caliber were constantly lubed prior to feeding into the guns. M16s and M14s were lubed (oiled) in the receiver groups (receiver housings). When the guns fired, a mixture of heat, and burnt gunpowder, all mixed with the burning oil to become permanently embedded into the GI's memory for years to come. That mixed with the scent of a tank's diesel engine and some crushed jungle leafs (vegetation) make for some memorable evenings.
US Army M1 steel helmets were not issued with cloth camo covers as were the US Marines fighting in the Pacific, during WWII. Consequently, soldiers didn't do to much writing on steel. The common thing was to paint their division patch on the sides of the helmets (1st Infantry Division, 3rd ID, 4 ID, etc.). In Vietnam, the US Army began, for the first time, issuing cloth camo reversible covers for the steel M1 helmets. At this time US Soldiers began writing graffiti on their helmets.

Soldiers typically wear tin hats, also known as steel helmets, for protection during combat. These helmets were commonly used in World War I and World War II, providing defense against shrapnel and debris. Modern military forces have transitioned to advanced materials for helmets, but the term "tin hat" often refers nostalgically to those earlier designs. Today, soldiers wear helmets made from materials like Kevlar or ballistic nylon for improved safety and comfort.
Very little or none at all apart from steel helmets

North Vietnam also drafted it's men; captured NVA pith helmets had graffiti written on them that read in Vietnamese, "Born in the North, died in the South."

All combatants in WWII were supplied with steel helmets. But only the US and USSR steel helmets survived into the Vietnam War era; both the US and USSR steel helmet "DESIGNS" served in the Vietnam War.
Soldiers wore leather helmets inside tanks for protection against head injuries caused by bumps and jolts during movement. The helmets helped cushion the impact and reduce the risk of injury.

They wore helmets long before world war 1.
In the film "Platoon," characters often write personal messages or names on their helmets as a way to express individuality and maintain a connection to their identity amidst the chaos of war. These inscriptions serve as a form of morale-boosting and a reminder of home, highlighting the soldiers' humanity in a dehumanizing environment. The helmets become a canvas for personal stories and a reflection of the soldiers' experiences and emotions during the Vietnam War.
Not all gas masks are compatible with helmets, so some soldiers forgo helmets to wear their masks.
