Looks like Ajax will be primarily for reconnaisance. IFV variant will not exist.
So there will be various versions of the AJAX armored fighting vehicle:
All variants can pick between these for a secondary Remote Weapon Station (RWS):
7.62 mm General Purpose Machine Gun (GPMG), 12.7 mm Heavy Machine Gun (HMG), or 40mm Grenade Machine Gun (GMG)
AJAX regular - 40mm stabilized cannon, direct fire support, reconnaissance.
ATLAS - recovery option with 30 metric tons of winching power.
ARGUS - battlefield engineering variant.
ATHENA - command and control variant.
APOLLO - a 5 ton crane repair variant.
ARES - specialist troop carrier.
The British Armies fleet of 589 AJAX is currently housed/gone through testing at Salisbury Plain and is said to be ready for full deployment. Next year it's suggested that AJAX will be able to be operationally deployed and issued to troops, so far reports say it's nimble and reliable and an improvement over the CVRT's they were last issued for this role. The CVRT being an analog system compared to the AJAX's digital systems.
