Does the base not have a car club/garage to rent scheme where you can put your car under cover for the 6 weeks? Otherwise, +1 on pumping up the tyres, leaving it in gear and handbrakes off. Mine is put away each winter for 3 -4 months, and apart from the tyres and in-gear, I also put in a dehumidifier, trickle charger and cover. Don't think 6 weeks is a problem...
And good luck with the deployment
