In the immediate aftermath of Mrkonjic Grad ' s fall, the VRS had already shifted the veteran 16 th Krajina Motorized Brigade - - probably best brigade in the RS - - to Manjaca. 835 If the VRS believed an HV operation against Banja Luka was imminent, the Main Staff would most likely have transferred all available reserves to the Manjaca area, building up a force that could have numbered at least nine and maybe 11 brigades, including a full-armored brigade, with upward of 15,000 to 20,000 troops. 836 The VRS would have verly likely fought even harder for Banja Luka than the SVK did at Knin, for they would not have been encircled.
