The agreement allows for the potential supply of up to 500 RCH 155 self-propelled howitzers. Moreover, deliveries under this agreement may be made not only to the Bundeswehr but also to foreign customers. While 500 RCH 155s is an impressive number, the Bundeswehr probably does not need that many at present.
Can you imagine trying to fight against an enemy who has 155mm artillery that can fire on the move operated by crews within an armored hull? How do you even begin to counter that or develop threatening counter artillery battery doctrine?
You counter it with your own?
Now neither of you can easily hit each other, and both suffer the same problems.
