Was Steinbeck’s “The Moon is Down” an inspiration for Joseph Heller’s “Catch 22”?

Consider this passage (Steinbeck describing a Nazi officer):

If Captain Bentick was too old to be a captain, Captain Loft was too young. Captain Loft was as much a captain as one can imagine. He lived and breathed his captaincy. He had no unmilitary moments. A driving ambition forced him up through the grades. He rose like cream to the top of milk. He clicked his heels as perfectly as a dancer does. He knew every kind of military courtesy and insisted on using it all. Generals were afraid of him because he knew more about the deportment of a soldier than they did. Captain Loft thought and believed that a soldier is the highest development of animal life. If he considered God at all, he thought of Him as an old and honoured general, retired and grey, living among remembered battles and putting wreaths on the graves of his lieutenants several times a year. Captain Loft believed that all women fall in love with a uniform and he did not see how it could be otherwise. In the normal course of events he would be a brigadier-general at forty-five and have his picture in the illustrated papers, flanked by tall, pale, masculine women wearing lacy picture hats.
