On 18 March while advancing to contact, the lead elements of the company became engaged by the heavy automatic weapon, heavy machine gun, rocket propelled grenade, Claymore mine and small-arms fire of an estimated battalion-size force. Capt. Bucha, with complete disregard for his safety, moved to the threatened area to direct the defense and ordered reinforcements to the aid of the lead element.

Bucha crawled through the hail of fire to single-handedly destroy the bunker with grenades. During this heroic action Capt. Bucha received a painful shrapnel wound. Returning to the perimeter, he observed that his unit could not hold its positions and repel the human wave assaults launched by the determined enemy. Capt. Bucha ordered the withdrawal of the unit elements and covered the withdrawal to positions of a company perimeter from which he could direct fire upon the charging enemy. When 1 friendly element retrieving casualties was ambushed and cut off from the perimeter, Capt. Bucha ordered them to feign death and he directed artillery fire around them. During the night Capt. Bucha moved throughout the position, distributing ammunition, providing encouragement and insuring the integrity of the defense. He directed artillery, helicopter gunship and Air Force gunship fire on the enemy strong points and attacking forces, marking the positions with smoke grenades.
