The Gills will play Dover Athletic in a pre-season friendly at Crabble on Tuesday July 14, with kick-off scheduled for 7:30pm.
This is the second fixture that has been confirmed for the first-team with a game against Ebbsfleet at the Kuflink Stadium already planned for Friday July 31 (7pm).
A Gills XI will go to Sheppey on the same night as the Dover game, with another XI set to take on Lewes at the Dripping Pan on Tuesday July 21.
Dover, now under the management of Jake Leberl, are in the National League South and finished 20th in the table last season.
Ticket information for the game will be released nearer the time.
