Jesus took part in this Himself!
Doesn't the Watchtower know that Jesus was well aware of what the "servant" of the centurion would do if He healed the servant?
The "healed servant" would continue to aid the centurion in preparing for "Military Duties"! ( No matter what job the servant had, anything he did for the centurion was going to aid the centurion. Whether the servant cooked his meals, shined his boots, cleaned his weapons, or whatever, he was still going to be in service to aid the centurion in one way or the other.)
It doesn't take a rocket scientist to know what the servant of the centurion was going to do "after" Jesus healed him. He was going to do what he always did.
Help the centurion in completing military duties. Doesn't the Watchtower know how to read?
Luke 7: 1-10
Jesus Heals a Centurion's Servant
7 After he had finished all his sayings in the hearing of the people, he entered Capernaum. 2 Now a centurion had a servant[a] who was sick and at the point of death, who was highly valued by him. 3 When the centurion[b] heard about Jesus, he sent to him elders of the Jews, asking him to come and heal his servant. 4 And when they came to Jesus, they pleaded with him earnestly, saying, “He is worthy to have you do this for him, 5 for he loves our nation, and he is the one who built us our synagogue.” 6 And Jesus went with them. When he was not far from the house, the centurion sent friends, saying to him, “Lord, do not trouble yourself, for I am not worthy to have you come under my roof. 7 Therefore I did not presume to come to you. But say the word, and let my servant be healed. 8 For I too am a man set under authority, with soldiers under me: and I say to one, ‘Go,’ and he goes; and to another, ‘Come,’ and he comes; and to my servant, ‘Do this,’ and he does it.” 9 When Jesus heard these things, he marveled at him, and turning to the crowd that followed him, said, “I tell you, not even in Israel have I found such faith.” 10 And when those who had been sent returned to the house, they found the servant well.
