QRF improvements

[StefArma]

To allow to reduce even more the garrison troops and predilige quality over quantity, it's gonna be necessary to call in QRF while the enemy units are under attack rather than after FIA capture.

This could require another parameter in calling QRF

now the script located in \Create\patrolCA.sqf accept the passing of:

• marker ("base_1") or position (getpos player)
• force departing marker (actually not used in the code.

It's my intention to enhance it to accept

• A) small (true)
• B) defense (true)

A) would send qrf on foot in order to replace the killed units in towns
B) would send qrf while player is attacking a military emplacement.
