by the platoons before they took up their position along the northern end of the base to seal off that escape route. Of the four main paratrooper companies, D-Company had experienced the most accurate drop, though they were still 500 m from their intended drop zone. Regrouping quickly, they moved to attack structures which had been identified in the aerial reconnaissance photos as engineering buildings. However, during the assault on these buildings several of them exploded, perhaps due to ammunition stores within, injuring several paratroopers. There was also a brief blue-on-blue engagement as D-Company paratroopers were mistakenly fired upon by their fellow soldiers from B-Company, which by then had reached the base, but there were no casualties. After completing the assault of the engineer complex, D-Company moved south to set up a stop-line and prevent any guerrillas from escaping via that route. It also dispatched the anti-tank platoon to lay a tank ambush on the road to Techamutete. 09h00 – 12h00 By 09h00, A and B Companies had regrouped and were ready to commence the main assault on Cassinga. Instead of attacking eastwards as initially planned, the two companies attacked the base in a northerly direction. Initially, they encountered very little resistance, though this changed dramatically once the paratroopers neared the centre of the base. Heavy sniper fire was directed at the paratroopers from a number of trees inside the base, they were subjected to B-10 recoilless rifle fire, and some SWAPO guerrillas had regrouped, using houses as cover from which to fire at the paratroopers, critically wounding two paratroopers. However, the paratroopers faced their greatest challenge when they were fired upon by a number of ZPU-2 14.5 mm multi-barrel anti-aircraft guns used in the ground role. This brought both companies to a complete halt, as they were unable to move under the accurate, and close, fire of the guns, and the Buccaneer on CAS duty could not conduct a strike on the guns for fear of hitting the paratroopers close by. In the end, Colonel Breytenbach ordered the commander of D-Company to take some men and work up towards the guns by attacking the trenches to the west of Cassinga. He also ordered the mortar platoon to begin attacking the guns. Upon entering the trenches, the men from D-Company were surprised to find a number of civilians, whom they later asserted were being used as human shields by the
