request for support of D Company At 17:02, Smith reported D Company was running low on ammunition and required aerial resupply. With just three magazines carried by each rifleman, they were only lightly equipped prior to the battle. This was a standard load calculated on 1 RAR usage rates which had been enough during previous actions, but it proved insufficient for sustained fighting. Due to the thick vegetation, the ammunition boxes would need to be dropped through the trees, and intending on moving his headquarters behind a low knoll, Smith nominated a point west. This position would afford greater protection, while the helicopters would be less likely to attract ground fire. Yet with their casualties now unable to be moved, D Company would have to remain where it was. Townsend passed the ammunition demand to Headquarters 1 ATF. In response, Jackson requested two UH-1B Iroquois from No. 9 Squadron RAAF to deliver it; however, the senior RAAF officer at Nui Dat, Group Captain Peter Raw, was not prepared to risk aircraft hovering at tree-top height in the heavy rain where they would be exposed to ground fire, citing Department of Air regulations. Relations between the Army and RAAF over the use of the helicopters had become increasingly bitter in the preceding months, and were still tenuous despite recent improvements. Jackson requested American assistance, and when the US Army liaison officer responded more favourably, Raw felt no alternative than to accede to the original request, offering to effect the resupply instead. By coincidence, two RAAF Iroquois were available at Nui Dat, having been used for the concert. Smith called for the waiting aircraft to drop napalm across 11 Platoon's eastern frontage. The Phantoms soon arrived, but the rain and low cloud obscured the coloured smoke the Australians had thrown to mark their position through the trees. Stanley was forced to halt the artillery while the aircraft flew overhead, but as Smith was unable to establish communications with the forward air observer he wanted the aircraft to move out of the area so it could resume firing. Townsend directed the aircraft to attack the forward slopes of Nui Dat 2 instead, believing the VC command element to be located there. The artillery fire recommenced as the VC formed assault waves. Major Harry Honnor—officer commanding 161st Battery, RNZA attached to 6 RAR in direct support—served as Townsend's artillery advisor at Nui Dat and
