US Army completes Iron First active protection system trial on Bradley IFVI have only seen one example of IFV with APS actually being used, that is Hungary - And they are not exactly role models. Even Israel, who pioneered APS tech, chose not to put them on most of its IFVs. (though even if they do do it in the future, it would still not apply to our situation since their IFV is more armoured than their MBT). Rest all have trials and stuff, dont see large scale adoptions.
The entire point of IFVs is to operate in close proximity to troops - If you separate the two, IFV is just reduced to a shitty tank with seating capacity :/
Primary offensive and defensive power of IFV is the troops it carries, not the armour or munitions. It is not the spear, the troops are the spear. IFVs are supposed to provide covering fire while the troops seize the objective.
Another thing to keep in mind - IFVs , and armour in general, is not meant to be invulnerable - All these systems (APS, heavy armour, ERA, sensor data) are just meant to increase survivability. In the end, these can all be defeated, and ever since armour came on to the battlefeild back in WW1, there were cheap counters to it.
Sums it up pretty nicely:-
"Ask not what you can do to the tank - Ask what the tank can do to you"
Same goes for IFVs.
3 IFV/APC with APS - Namer, lynx, Bradley.In 2016, the Army chose to test the Iron Fist lightweight decoupled system to protect its medium- and light-armored vehicles. Initial testing in 2018 was to validate the vendor’s (General Dynamics and Elbit Systems, Inc.) performance claims. Congress provided additional funding in fiscal year 2022, toward the goal of equipping an entire Army brigade of Bradley vehicles in 2025 with continued funding.
Also majority of MBT in the world lacks APS. IA having zero APS equipped vehicles[MBT].
