Pretty much. But there were also Red Teams, with even more serious firepower from above.

Are the Pink Teams you are referring to something like this?
Air cavalry troops often provided surveillance of an extended area around a stationary or moving force. Pink teams maintained radio contact with the ground commander and reported enemy positions, trails, or troop sightings in order that appropriate action could be taken. Pink or red teams were capable of engaging the enemy with their own organic weapons and of adjusting artillery and air strikes to reduce an enemy threat.
When conducting first-light reconnaissance around a unit field location, the pink teams began their flights before daybreak to be on station at first light. En route the team leader contacted the ground unit commander to request artillery advice and to ask whether the ground unit had any particular area of interest. Last-light reconnaissance began an hour and a half before dark in order to be completed by nightfall. When a target was discovered, the team reported to the ground unit responsible for the area and requested clearance to fire. All enemy sightings were reported to the unit in whose area the teams were operating.
Artillery raids supported by air cavalry units included both the tube and aerial rocket artillery raids, delivered into areas where the enemy considered himself safe from such fire. During a tube artillery raid, the air cavalry troop reconnoitered the selected landing zone and secured it with an aerorifle platoon before artillery was landed by CH-47 and CH-54 aircraft. Pink teams conducted visual reconnaissance to develop targets of opportunity and were capable of adjusting fire and conducting immediate damage assessment.
A pink team was a mixture of red and white, one light observation helicopter and one Cobra. The observation helicopter followed trails, made low passes over the enemy positions, and contoured the terrain in conducting its reconnaissance mission. The gunship flew a circular pattern at a higher altitude in the general vicinity to provide suppressive fire and relay information gathered by the observation helicopter. When outside of artillery range or in areas considered to be extremely dangerous, the pink teams were used in conjunction with a command and control helicopter. If one helicopter was downed by enemy fire, the remaining aircraft provided cover until a reaction force arrived. Pink teams could also adjust artillery fire, although the AH-1G with its twin pods of 2.75-inch rockets was comparable to a 105-mm. howitzer. Pink teams were the most prevalent tactical combination of aircraft in the air cavalry troop.
Fire base construction missions involved an aerorifle platoon, an engineer team, and a pink team. The aerorifle platoon was inserted (by rappel, if necessary) into the proposed landing zone to provide security for the engineers. After a landing zone had been cleared for one ship, additional engineer equipment was landed to enlarge the area to the required fire base dimensions. Pink teams conducted screening operations around the troop elements; co-ordination was achieved through a command and control aircraft. After a one-ship landing zone was prepared, infantry troops were usually brought in, and the aerorifle platoon could then conduct reconnaissance of likely enemy positions in the vicinity. This platoon was also capable of conducting limited combat assaults and ambushes. When teamed with scout and aeroweapons platoon elements of the air cavalry troop, it constituted a balanced combined arms team.
